Error 504: https://graph.microsoft.com/beta/privilegedAccess/aadGroups/resources/{group-id}/roleAssignments

Question

Hello! We have a runbook automation that worked correctly until now, which launches a query to the groups that have PIM enabled, to get the groups that are associated with them as "eligible". We obtained the information about the groups that have PIM enabled and their assignments with the following Graph URL: https://graph.microsoft.com/beta/privilegedAccess/aadGroups/resources/{group-id}/roleAssignments

But now we are receiving a 504 error. We supposed that something change as the URL is in BETA, but reviewing the documentation we cannot get this information. Could someone help us?

Thank you!
