Hello there,
Getting a BadRequest “Endpoint Not Found” while trying to add an ARM TAG (through a PATCH) into a Microsoft.OperationsManagement resource:

"/subscriptions//resourceGroups/<ResourceGroup/providers/Microsoft.OperationsManagement/solutions/Security(DefaultWorkspace-GUID)"

I wasn't sure if that was because of the parenthesis " ( " and " ) " in the resouce name - of if because there's no PATCH keyword in https://github.com/Azure/azure-rest-api-specs/blob/master/specification/batch/resource-manager/Microsoft.Batch/stable/2017-09-01/BatchManagement.json
