Unable to attach files to HR Case (sn_hr_core_case) in specific instance, but able to in all others. Why?Issue When the user attempts to attach a file to a HR Case, the modal shows that is attempting to attach. However, then, the modal just returns to being blank as if no attempt was made to attach a file. Also, no attachment is shown in the header of the HR Case.CauseThe "Read" operation ACL for sys_attachment for HR Core has been customized and is now broken.ResolutionAs mentioned above, the read ACL for sys_attachment in the HR Core scope was modified by a non-ServiceNow user. Reverting this ACL back to the Out of Box (OOB) version resolves the issue. For convenience, here is a link to the ACL: /sys_security_acl_list.do?sysparm_query=nameSTARTSWITHsys_attachment%5Esys_package%3Dd4ac3fff5b311200a4656ede91f91af2%5Eoperation%3Dread
