I have started learning Video SDK and have failure in creating session. When I run the sample program and create the session, it shows the camera capture for a short time, then shows a message: Unable to join or create session.Please try again.(Error Code: 2009) The SDK documentation says about this error code: ZoomVideoSDKErrors\_Meeting\_Not\_Started 2009 The Session that you are trying to start did not start successfully. Please try again. I tried again many times and the code is still the same. Could you please tell me what should I do to proceed? ---

Hi @jacob281, thanks for using the dev forum. Can you please provide some additional context around how you’re trying to join the session? At a minimum, we would need the JWT you’re passing into the SDK, the session name, and the version of the SDK you’re using. Thanks! ---

Hi. I am running exactly the demo app as is, without any modifications: zoom-video-sdk-windows-1.2.2\Sample-Libs\x86\demo\videosdk\_demo\videosdk\_demo.sln. SDK version is v1.2.2 (1185), as shown in the file zoom-video-sdk-windows-1.2.2\version.txt. Session name is s1. Token: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhcHBfa2V5IjoiOVJWdVNGZk5QamNhT3VMVjk2Zk5sbjZRVkUxREEzOElKMEFxIiwidmVyc2lvbiI6MSwicm9sZV90eXBlIjowLCJpYXQiOjE2NDgwNjc4MzAsImV4cCI6MTY0ODE1NDIzMCwidHBjIjoiczEifQ.iYzaMUfxnJon5j7Onn88NghnwqP517nGAr6TlvdJ-eQ Thank you. ---

Hi @jacob281, Thanks for the additional information. You are seeing this error due to the `role_type` field being set to 0. Currently, if you try joining a session as a regular participant, it will fail unless the host has already started the session. If you change the `role_type` value to 1, you should be able to start the session. It is also worth noting that the SDK’s behavior will change in a future release to allow regular participants to join sessions before the host has started them. Thanks! ---

Thank you very much. I changed role\_type to 1 and it worked. ---
