Some more additional info… In my corporate zoom account, which I was using tor the Zoom API, I didnt see the channel tab (saw only the contacts tab in the UI). This made me think there is something specific to the account due to which I cannot call the create channel API. So, I created a new API tried to my gmail account. I still get the same 500 error when creating a channel from my gmail account, inviting another gmail user. Running out of ideas on how to troubleshoot this issue.
