Descrição
getBase64FromMediaMessagerecebemos um erro de download.message.upsertfoi super positiva, mas nos momentos em que recebo os erros 400 e 403 com a descrição de No matching sessions found for message, Bad MAC, failed to decrypt message ou SessionError, impede o re-processamento de do evento no retry da Baileys. Isso causa em certas situações o impedimento do processamento das primeiras mensagens até que a sessão e tokens de descriptografia estejam validos.Solução
trydos eventosmessage.upsert.downloadContentFromMessageapós erro ao tentar baixar com o métodogetBase64FromMediaMessage. (Por algum motivodownloadContentFromMessagefunciona melhor.)Summary by Sourcery
Handle transient Baileys decryption errors by filtering specific message stub parameters before processing and improve media download reliability with a retry fallback using downloadContentFromMessage.
