# 50437: Group Participant already exists

Log Type: APPLICATION

Log Level: ERROR

## Description

A participant matching this one already exists in the conversation.

### Possible causes

* An participant with the same ProxyAddress+Address pair already exists in this conversation
* A native GMMS Participant with the same Address exists in this conversation
* A Chat Participant with the same Identity and Project Address exists in this conversation

This error may result from a race condition, where a participant was inadvertently added twice.

### Possible solutions

* Add the participant with a different Address or Identity
* Ignore this error — your participant is already present.
