# 50438: Group conversation with given participant list already exists

Log Type: APPLICATION

Log Level: ERROR

## 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-classic/states-timers#closed-conversations).
* Alternatively, locate the other conversation and use that in place of this one.
