Intermittently duplicating message in Whatsapp Channel (Weak connection)

[Cauen]

Describe the bug

The agent reported that she had a weak connection, she only sent the message once and it showed twice in the chat

Consulting the logs, the system records 2 calls to Api::V1::Accounts::Conversations::MessagesController#create. Which means it's something in the frontend.

A few messages were duplicated. They were very personalized, which rules out the option of the agent sending them again unintentionally, but that had never happened since January, so it's a very rare case.

Would there be any retry logic that perhaps in some scenarios could make the message be sent twice?

I tried reproducing locally by activating a network throttle. But I could not.

Details: The difference between the messages was 12 seconds. It wasn't a private message. It was from Whatsapp Cloud. Both were sent to the customer because the database records 2 different "source_ids".

Chatwoot version: 3.4.0
Cloud: Hetzner (Not relevant i think)
