Description of Bug

I was working on a config where every custom service endpoint is present in the provider config, using a map to lookup the FIPS endpoint, read from a file. If not present, the endpoint value is null to use the default. This works fine for every service except two: prometheusservice and codestarnotifications . For these two, I get an error that the "Argument named is not expected here."

Actual Behavior

❯ terraform plan
╷
│ Error: Unsupported argument
│
│   on main.tf line 3, in provider "aws":
│    3:     prometheusservice     = null
│
│ An argument named "prometheusservice" is not expected here.
╵
╷
│ Error: Unsupported argument
│
│   on main.tf line 4, in provider "aws":
│    4:     codestarnotifications = null
│
│ An argument named "codestarnotifications" is not expected here.
╵

Steps to Reproduce

1. terraform plan

These 2 need to be added to EndpointServiceNames in internal/provider/provider.go.

This is all moved now to internal/conns/conns.go and should be resolved soon.
