You don’t have an else case for when your if statement is not true. This gives a null service → error.

If you don’t have another service to run when the if test is not true then don’t use a service template.

Put the test as a template condition (or use numeric state conditions) and just put your service in the actions. It won’t run if the conditions don’t pass.
