This is the source of the failure and the Group Tree is not loaded.If opened by user with "admin" role, the Group Tree is populated.Release or EnvironmentCurrent supported versions.CauseIn most cases, the issue is caused by user is not able to query/open the records in the cmdb_ci_service_group table such as the record for the "ALL" group, which is the default root parent.This is normally caused by the existence of "Before Query" Business Rule that restrict users from opening the record. In case the user is able to open cmdb_ci_service_group record for "ALL" , check if there is extra restriction on "ALL" service group in the sa_svc_group_responsibilities table.ResolutionAs admin, go to /cmdb_ci_service_group_list.do and open the 'ALL' record From the menu, select Configure > All Go to the "Business Rules" TAB and select the active ones where query=true. Find the custom Query Business Rule is affecting. It could be on the cmdb_ci table. In addition (If applies), delete any restriction on "ALL" group in the sa_svc_group_responsibilities table. There should be no restriction on this record.Additional InformationChecking the node log will give the following output: 2022-03-08 01:04:38 (052) Default-thread-15 2E49F5EE874A4950181184490CBB3506 txid=8999392e870a #86630 [REST API] BatchItemExecutor : *** Start batch item /api/sn_nocpit/nocpit/GroupTree?timestamp=1646730235000&includeBusinessServices=true with id=cl0hwoufx0004_uxf0yzkxhyf2022-03-08 01:04:38 (053) Default-thread-15 2E49F5EE874A4950181184490CBB3506 txid=8999392e870a User agent with HTTP/1.1 and no encoding: null2022-03-08 01:04:38 (064) Default-thread-15 2E49F5EE874A4950181184490CBB3506 txid=8999392e870a BusinessServiceManager: Service group id 0e7a06157f10310016181ccebefa91ce is not permitted for roles sn_request_read, .......,evt_mgmt_operator,cmdb_read,dependency_views2022-03-08 01:04:39 (201) Default-thread-15 2E49F5EE874A4950181184490CBB3506 txid=8999392e870a SEVERE *** ERROR *** Impact Calculation: Predefined 'All' group was not found2022-03-08 01:04:39 (203) Default-thread-15 2E49F5EE874A4950181184490CBB3506 txid=8999392e870a Couldn't decipher the stack trace resulting from the following JavaScriptException:
