## Description

Requested Chat User not found

### Possible Causes

Chat User related to a Chat Channel could not be found.

### Possible Solutions

Chat User is created automatically by Flex for any inbound end customer requests and automatically when an Agent connects to Flex where that Agent already does not have a Chat User. Chat User is synchronized to Identity Provider provided information (via SSO) on role and name. Please try again and ensure that the relevant Chat Users are not removed in your own implementations.
