 Define a role assignment for the system-assigned identity:
 
 ```azurecli
-az cosmosdb sql role assignment create --account-name $cosmosdbname --resource-group $resourcegroup --role-definition-id $readOnlyRoleDefinitionId --principal-id $sys_principal --scope $scope
+az cosmosdb sql role assignment create --account-name $cosmosdb_acc_name --resource-group $resource_group --role-definition-id $readOnlyRoleDefinitionId --principal-id $system_assigned_principal --scope $scope
 ```
