Fail to fetch user info occasionally - have anyone seen it?

[MosheMaorKaltur]

I encounter a case where api calls to get user info in meeting failed with error 'missing scope' while my application contains this scope and it worked with the defiend scope for the last 8 years, I just wonder if its just a wrong indication for timeout access token? had anyone seen it?

Hello @MosheMaorKaltur,

Welcome to the Zoom Community! We're glad to have you here!

The "missing scope" error when making API calls to get user info in a meeting typically means that the access token being used does not have the required scope, even if your app is configured with that scope. This can happen for a few reasons:

1. The access token has expired or is invalid. In this case, you may see misleading errors like "missing scope" instead of a clear "token expired" message.
2. The user or admin may have removed the app or changed permissions, so the token no longer has the necessary scopes.
3. The app was updated, and the new scopes were not reauthorized by users.

To resolve this:

• Try refreshing the access token and ensure you are using a valid, up-to-date token.
• Double-check that the required scopes are still granted to your app in the Zoom App Marketplace.
• If you recently added new scopes, users may need to reauthorize the app.

This issue is not uncommon, especially if tokens expire or permissions change. If refreshing the token does not resolve the issue, review your app’s scopes and reauthorization process.
