Aria Operations for Log Swagger API triggering Error code 500: Internal Server Error when performing GET/User with showDetails set to True. Note that showDetails set to False will work fine. The error has to do with user no longer in the AD/vIDM and queried upon, it will throw a generic error out without much details to the API UI. The unknown user account can potentially blocking out valid user accounts as well with the same error.
Log will indicate the AD user through Workspace One that is no longer valid. In this case, ASUSER123 no longer in the AD but still exists in Aria Operations for Log.
Multiple or no users with name <ADUSER123> found in domain DOMAIN.NAME.COM. Workspace ONE Access hostname: HOST123.DOMAIN.NAME.COM, tenant:, clientId:XXXXXX-XXXX-XXXX-XXXXXXX-XXXX
