PROGRAMMABLE CHAT
ERROR
There is an existing group conversation with the same participant list.
- You previously created a conflicting conversation
- Twilio created a conversation — which now conflicts — in the course of Autocreation.
- If the existing conversation is no longer in use, delete or close the conversation.
- Alternatively, locate the other conversation and use that in place of this one.
