Invalid access token error code 124

Hi team,

I’m facing the error “Invalid access token” while trying to create a new meeting via the API. I’m using Server-to-Server OAuth and I can generate a token successfully. However, when I attempt to create a meeting using this token through the following endpoint:, I receive the above error message. I’m unsure how to resolve this issue.

Note that I sending the token like this
'Authorization' => 'Bearer ' . $accessToken,

Can you try using a userID instead of me in the endpoint?

I am also having similar issues with JWT app. Everything was working a few days ago and then stopped. Nothing has changed on our side.
