4711 error when calling accounts endpoint with Server-to-Server OAuth

We are seeing a 4711 error when calling the accounts endpoint using Server-to-Server OAuth.

The other day, the system we implemented stopped working properly. When we checked, we found that the Server-to-Server OAuth app used by the system had been disabled.

We activated it again in order to restore the system, but after that, we were no longer able to retrieve sub-account information (/accounts?page_size=…) due to the following 4711 error:

{"code":4711,"message":"Invalid access token, does not contain scopes:[account:read:list_sub_accounts:master]."}

We did not change the scope settings when we reactivated the app.

We would like to allow the scope mentioned in the error, account:read:list_sub_accounts:master, but this scope is not included in the selectable scope list.

This system was working until last month, and this error did not occur at that time.

We are a Zoom reseller, and we need this API for customer management.

Could you please advise how we can resolve this error?
