/v1/company/employees/attributes returning 403

Hi!

/v1/company/employees/attributes started returning 403 for us when using a specific API key. Meaning it still works fine with other keys. The message body reads "Your account has expired.", even though the same API key can still be used to read other data such as employees/persons. I cannot find any relation to attributes on the API credentials settings page either. What can be wrong?

Cheers / Fredrik
