Twilio channel sending messages after substantial delay

[jlangree]

Describe the bug Bots set up with the Twilio channel often fail to send the messages until much later. Often by the time it is actually sent, the user has already said something else, which causes issues if the bot is asking questions.

• Delays in sending messages are up to 15 minutes. and sometimes messages are sent out of order.
• The before-outgoing-middleware is running.
• This issue is occurring with two different Botpress instances, using two different Twilio phone numbers.

To Reproduce Set up a bot to use the Twilio channel. Occasionally this will happen. Not all the time, but it appears to occur about every other conversation session.

Expected behavior The messages are sent via Twilio within 10 seconds or so.

Environment (please complete the following information):

• OS: Linux server running Botpress on Docker
• Botpress Version - 12.28.0
