Hi Will thank you for your answer,
All our meetings are created by the same script but only a few portion of them throws this error.
It seems that we don’t fall under these scenarios because this script create meeting with type 2 (scheduled) and it does not change the host. (6 yesterday out of +2300 and no one before the past 6 months)
We can’t access the meeting via zoom backend (even when trying to edit the meeting - see the screenshot attached).
The only temporary fix we are able to use is to manualy delete the corrupted api user + meeting (each api user hosting a meeting) and the script recreate the api user and his meeting exactly with the same parameters as before, but this time it works.
We just kept this user and meeting for you to be able to debug (https://us02web.zoom.us/user/eXSsVXQUStWPlO6WQfB0cQ/meeting/81004884896).
