Summary

ServiceAPI using OAuth causes log-level error messages referencing token expiration. The message should not be Error level as it is not server-side and does not require Administrator's action. The frequency of the error overpopulates Pega Diagnostic Cloud and obscures more relevant errors. When the OAuth access token expires after a day, excessive logging of authentication failures happens in the log.
