Not able to join meeting in sample web app

I followed the steps given in https://marketplace.zoom.us/docs/sdk/sdk-reference/web-reference to make a sample web app but I am not able to join meeting after entering my meeting id and name. I have attached screenshots.

Hey @1997sprocks,

Can you please share the error in the console?

Also make sure you are using a JWT App Type for the key and secret.

Thanks,
Tommy
