From the docs for apply function - “This function will only be called execution of a ‘pulumi up’ request. It will not run during ‘pulumi preview’ (as the values of resources are of course not known then). It is not available for functions that end up executing in the cloud during runtime. To get the value of the Output during cloud runtime execution, use get().”

Ok thanks, so I must have been doing something wrong here. I'm creating a `k8s.core.v1.Service` resource and calling apply on it's `metadata.name` property, which is an `Output`. If I run `pulumi preview` the callback gets called with `undefined` as value. Am I understanding something wrong here?

Sorry, forget it. I misused deepmerge somewhere in between which caused my problem.
