+## Error during managed identity assignment operations
+In rare cases, you may see error messages indicating errors related to assignment of managed identities with Azure resources. Some of the example error messages are as follows: 
+- Azure resource ‘azure-resource-id' does not have access to identity 'managed-identity-id'.  
+- No managed service identities are associated with resource ‘azure-resource-id'
+- Managed service identities referenced with URL 'https://control-....virtualMachineScaleSets/<vmss_name>/credentials/v2/systemassigned' are not valid. Ensure all assigned identities associated with the resource are valid.
+
+**Workaround**
+In these rare cases the best next steps are
+
+1. For identities no longer needed to be assigned to the resource, remove them from the resource.
+2. For User Assigned Managed Identity, reassign the identity to the Azure resource. 
+3. For System Assigned Managed Identity, disable the identity and enable it again.
