Sendbird Bots do not call the webhook

Sendbird Chat API/SDK API

[Problem/Question]
We’ve set up a sendbird bot pointing to an ngrok endpoint on a local device. Upon a user message, we see the message appear in the chat, the global chat webhook being called, but the bot’s webhook does not get called.

[SDK Version]
1.0.27
[Reproduction Steps]

  • create ngrok tunnel
  • Create Bot with bot_callback_url pointing to said tunnel
  • create GroupChannel with user and bot
  • send message from user
  • receive no callback

[Frequency]
// How frequently is this issue occurring?
Every time a message is sent

[Current impact]
// How is this currently impacting your implementation?
Unable to continue with implementation

I’ve checked that the ngrok address matches
the app id is 42F3640A-...

We’ve figured it out. It seems that there’s something going on with channel_invitation_preference. While stated to be default 0, using the current 1.0.27 python SDK, bots created with no channel_invitation_preference argument parsed are initialized with 1, instead of the 0 mentioned in the docs
