GRC AC 10.0 Auto provisioning failure

Hi experts

Please could you assist me with this issue. The customer is testing provisioning composite roles through GRC AC 10.0 and is getting the below

error. The design is that PRIVs are added in IdM 7.2 to identities and provisioning occurs from GRC AC10.0.

All GRC AC access requests are set to be auto approved.

Please could you let me know what "Illegal destination type 'H'" in the below screenshot means and how it can be fixed to allow auto provisioning of composite roles from GRC AC. What config changes are required (if any)  for this?

Please advise.

Thanks

Ranjit
