## Description

There is an existing group conversation with the same participant list.

### Possible Causes

- You previously created a conflicting conversation
- Twilio created a conversation — which now conflicts — in the course of Autocreation.

### Possible Solutions

- If the existing conversation is no longer in use, delete or [close the conversation](/docs/conversations/states-timers#closed-conversations).
- Alternatively, locate the other conversation and use that in place of this one.
