Accounts accessible through adwords API but not Google ads API?

[the...@funnel.io]

Hi,
During our work with migrating fully from the adwords API to Google Ads, we've noticed that one ad account belonging to one of our clients can be accessed through the adwords API, but when we try accessing it through the Google Ads API, we get the error "Authentication of the request failed.". Any idea why an account would be accessible only through one of the APIs? I can supply ID of the account and email of the user in a private message if needed.

Once again, the permissions on this forum seems to be a bit broken but I tried replying by email.
