Hey @moamd427

Thanks for using the dev forum!

The error code 150 represents `MobileRTCMeetError_InvalidArguments`.

Would you be able to share the code you are using to start a meeting so that we can troubleshoot together? Please omit any info you would not want the public to see.

Thanks!  
Michael
