If the type of identity is set to SystemAssigned, UserAssigned(w/space), Terraform will return the following 400 error even though the type has not changed when updating the resource. It is caused by the internal error (internal error: the legacy SystemAssigned,UserAssigned identity type should be being converted to the schema type - this is a bug). In this case, the type value returned from API is SystemAssigned,UserAssigned(no space) causing this internal error to occur.
Error:
`performing CreateOrUpdate: unexpected status 400 with error: InvalidResource: The resource definition is invalid.`
