Três correções para eliminar erro 479 em dispositivos vinculados:
1. Skip WAProto.Message.create() em generateWAMessageFromContent para carousel
- O carousel já foi processado com fromObject() (conversão profunda)
- O segundo create() faz cópia rasa que pode perder tipos protobuf nested
- Preserva a estrutura deep: cards > headers > imageMessage > nativeFlowMessage
2. Skip tctoken no stanza para carousel
- Implementações que funcionam não incluem tctoken para carousel
- Pode causar rejeição 479 em dispositivos vinculados (Web/Desktop)
3. Skip contextInfo.expiration (ephemeral) para carousel
- Se mensagens temporárias estão ativadas, contextInfo.expiration era
adicionado ao interactiveMessage, o que pode causar 479
- Implementações que funcionam não passam por generateWAMessageFromContent

Mudanças críticas para renderização do carousel em dispositivos vinculados:
1. Wrap carousel em viewOnceMessage para compatibilidade multi-device (MD)
2. Usar WAProto.Message.fromObject() ao invés de create() para conversão
profunda das estruturas nested (header, cards, nativeFlowMessage)
3. Adicionar root header com título no interactiveMessage
4. Retorno antecipado do carousel (sem messageContextInfo/reportingToken)
A diferença entre fromObject e create:
- fromObject: converte recursivamente objetos JS para tipos protobuf
- create: cópia rasa que pode não codificar corretamente estruturas deep
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
sendMessage adiciona messageContextInfo.messageSecret ao proto da
mensagem (para reporting token). Isso nao existe quando relayMessage
e chamado diretamente. O messageContextInfo ao lado de
interactiveMessage.carouselMessage causa erro 479 nos dispositivos
vinculados (Web/Desktop).
Agora o carousel pula a adicao de messageContextInfo, resultando em
um proto limpo: { interactiveMessage: { carouselMessage: {...} } }

Ajuste na estrutura do carrossel para renderizar na Web:
1. Removido viewOnceMessage wrapper - carrossel usa interactiveMessage direto
2. Biz node habilitado com native_flow v=9 name=mixed
3. Removido subtitle vazio e header vazio do nível raiz
4. Sem bot node (já estava correto)
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Comparação com Pastorini revelou que o biz node É NECESSÁRIO para
carrossel. Pastorini injeta exatamente:
<biz><interactive type="native_flow" v="1">
<native_flow v="9" name="mixed"/>
</interactive></biz>
Sem biz node = error 479. Com biz node = mensagem entregue.
O erro 479 anterior era causado por messageContextInfo no viewOnceMessage,
não pelo biz node em si.
Estado atual: biz node (SIM) + viewOnceMessage sem messageContextInfo +
bot node (NÃO para carousel/native_flow)
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
O código experimental de injeção do biz node tentava extrair botões de
interactiveMessage.nativeFlowMessage.buttons (nível raiz), mas no
carrossel os botões estão em carouselMessage.cards[].nativeFlowMessage.
Resultado: biz node injetado com buttonNames:[] e dados vazios,
WhatsApp via erro 479 rejeitando a mensagem nos dispositivos vinculados.
Pastorini usa relayMessage direto sem injetar biz node no carrossel.
Agora o carrossel pula a injeção do biz node completamente.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Mudanças baseadas na comparação com Pastorini:
1. Adicionado viewOnceMessage wrapper MÍNIMO (sem messageContextInfo)
- viewOnceMessage é obrigatório para Web/Desktop renderizar carousel
- messageContextInfo pode ter causado o erro 479 anterior
2. Removido campos extras que Pastorini não usa:
- Removido messageParamsJson dos cards
- Removido messageVersion dos cards
- Removido carouselCardType (Pastorini não define)
- Removido header vazio no nível raiz (Pastorini não envia)
3. Estrutura final:
viewOnceMessage.message.interactiveMessage.carouselMessage
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Two changes to fix carousel rendering on WhatsApp Web/Desktop:
1. Added carouselCardType: 1 (HSCROLL_CARDS) to carouselMessage - this
proto field tells the client how to render carousel cards. Without it,
Web/Desktop doesn't know to render horizontal scrollable cards.
2. Removed viewOnceMessage wrapper - confirmed it causes error 479
rejection from linked devices (Web/Desktop). Carousel works as
direct interactiveMessage on phone; carouselCardType should fix Web.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
WhatsApp Web/Desktop requires interactiveMessage to be wrapped inside
viewOnceMessage.message to render carousels fully. Without the wrapper,
only the header/body text is shown. The previous error 479 was caused by
missing messageVersion and empty messageParamsJson in cards, not by the
viewOnceMessage wrapper itself. Those card fixes are preserved.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Each carousel card's nativeFlowMessage was missing messageVersion and
had empty string '' for messageParamsJson instead of '{}'. This caused
error 479 on linked devices (Web/Desktop) while phone rendered OK.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Carousels wrapped in viewOnceMessage cause error 479 rejection.
Pastorini sends carousel as direct interactiveMessage which works
on all platforms including WhatsApp Web/Desktop.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
The <bot biz_bot="1"/> node prevents WhatsApp Web/Desktop from rendering
ALL native_flow button types, not just CTA. Quick_reply buttons had the
same issue: visible on smartphone only.
Confirmed: removing bot node fixes rendering on Web/Desktop for both
CTA buttons and quick_reply buttons.
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Empty name '' is rejected by WhatsApp server (error 405 in ack).
Reverted to 'mixed' which delivers successfully.
The key fix remains: no bot node for CTA-only buttons (Web compatibility).
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
- Changed native_flow name from 'mixed' to '' (empty) for all regular buttons
(both CTA and quick_reply), matching WhatsApp client traffic analysis
- Only special flows (payment_info, mpm, order_details) get specific names
- Fixed variable scope: moved hasCTA/hasQuickReply/isCTAOnly before if/else block
to ensure they're accessible for bot node conditional logic
- Removed duplicate CTA_BUTTON_NAMES/allButtonNames declarations
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
- Detect button types (CTA vs quick_reply) in nativeFlowMessage to set
appropriate native_flow name attribute: '' for CTA-only, 'quick_reply'
for quick_reply-only, 'mixed' for combinations
- Skip bot node injection for CTA-only buttons (cta_url, cta_copy, cta_call)
as the bot node prevents WhatsApp Web from rendering CTA buttons
- Keep bot node for quick_reply buttons which need it for response handling
https://claude.ai/code/session_01EK9NpViRCtda1WAvFd8ptR
Validates sections, rows, and string lengths before sending:
- Max 10 sections, 10 rows/section, 30 total rows
- Section title max 24 chars, row title max 24 chars
- Row description max 72 chars, row ID max 200 chars
- buttonText max 20 chars
- At least 1 section and 1 row per section required
Applied to all 3 list message paths: generateListMessage,
generateListMessageLegacy, and inline sections handler.
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
When title is not provided, the text was used as fallback for both
title and description, causing the header to appear twice. Now title
only uses an explicit title field, description uses text.
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
PRODUCT_LIST type requires WhatsApp Business catalog data and causes
error 479 for regular menu lists. SINGLE_SELECT is the correct type
for interactive menu lists with sections/rows.
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
getButtonType was returning undefined for listMessage, preventing
the existing product_list biz node from being injected. Changes:
- getButtonType returns 'list' for message.listMessage (line 632)
- getButtonType returns 'list' for innerMessage.listMessage (line 675)
- Exclude list messages from bot node injection (line 1325)
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
The viewOnceMessage > interactiveMessage > nativeFlowMessage wrapper with
single_select button was causing error 479 even with correct biz node.
WhatsApp requires the message to be in direct listMessage format (legacy)
paired with biz > list (type=product_list, v=2) node.
This matches the Pastorini implementation which sends:
- messageKeys: ['listMessage'] (NOT viewOnceMessage)
- biz > list (type=product_list, v=2)
The conversion extracts sections from nativeFlowMessage's single_select
buttonParamsJson and creates a proper listMessage with SINGLE_SELECT type.
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
The listMessage was getting error 405 because the biz node used
'interactive > native_flow' structure which is wrong for list messages.
Changed to use 'biz > list (type=product_list, v=2)' structure which
matches the Pastorini reference implementation and works on both
smartphone and web WhatsApp.
Changes:
- Differentiate biz node based on message type (list vs interactive)
- For listMessage/nativeList: use biz > list (type=product_list, v=2)
- For other interactive: keep biz > interactive > native_flow
- Skip bot node injection for list messages
- All listMessages (SINGLE_SELECT + PRODUCT_LIST) now get biz node
- Add diagnostic logging matching Pastorini format
https://claude.ai/code/session_01SJdSHiUxtwzV8bb5dedodb
Error 479 persisted even with correct listType. The issue is that
listMessage (legacy format) does NOT need biz node injection at all.
The biz node was causing the error. listMessage works natively without it.
Changes:
- getButtonType() returns undefined for message.listMessage
- No biz node is injected for list messages
- Keep listType as PRODUCT_LIST (from previous commit)
This should allow listMessage to be delivered without error 479.
https://claude.ai/code/session_01Vgu4xrsj8aUVCHWb4pmQPF
Error 479 was still occurring even with legacy listMessage format.
The issue is that listType must be PRODUCT_LIST (not SINGLE_SELECT)
to match the biz node type="product_list" v="2" that we're injecting.
This matches pastorini's working implementation exactly:
- listMessage with listType: PRODUCT_LIST
- biz node with type="product_list" v="2"
https://claude.ai/code/session_01Vgu4xrsj8aUVCHWb4pmQPF
The modern interactiveMessage format was causing error 479 (message rejection).
Switched to legacy listMessage format that matches pastorini's working implementation.
Changes:
1. **messages.ts**: Changed nativeList to use generateListMessageLegacy()
- Creates listMessage directly (not viewOnceMessage wrapper)
- Uses SINGLE_SELECT type (standard list)
2. **messages-send.ts**: Inject correct biz node for listMessage
- For buttonType === 'list': <biz><list type="product_list" v="2">
- Matches pastorini's working structure
- Removed checks that skipped biz node for listMessage
Why this works:
- Legacy listMessage + product_list biz node = accepted by WhatsApp
- Modern interactiveMessage + native_flow biz node = error 479
- This matches the pastorini implementation that works on Web/iOS/Android
