**Meeting SDK Type and Version**  
Meeting SDK type: Windows SDK  
Meeting SDK version: 5.10.3.4873

**Description**  
Calling IMeetingParticipantsController::ChangeUserName for current user from within IMeetingParticipantsCtrlEvent::onUserJoin callback sometimes returns SDKERR\_WRONG\_USAGE.

One thing that I noticed when this happens is that calling IUserInfo::IsHost returns false for host of the meeting. This does not happen every time, but once in 10 meetings.

**Error?**  
SDKERR\_WRONG\_USAGE

**How To Reproduce**  
_Steps to reproduce the behavior including:_

1. Use custCreate account with ZAK for login
2. Join someones meeting with that account
3. Call ChangeUserName within onUserJoin callback for your custCreate account
4. Occasionally observe failure

Acually now I have encountered another instance where error code is: SDKERR\_INTERNAL\_ERROR and SDKERR\_TOO\_FREQUENT\_CALL. Is there any good documentation around it

Hi @bogdan.lytvynovskyi ,

Thanks for the post, I’m happy to help here! Only the host or co-host can change other users’ names, could you confirm if the SDKERR\_WRONG\_USAGE error code only occurs when the user is no longer a host?

You can find the documentation of error codes there:

The user is never a host, but API works 99% of times. It only changes it’s own name, and sporadically fails
