resource `apstra_telemetry_service_registry_entry` - not all `storage_schema_path` values allowed?

I'm not clear on the rules which relate application_schema to storage_schema_path, but I'm having a problem creating one of these resources:

resource "apstra_telemetry_service_registry_entry" "t" {
  service_name       = "foo"
  application_schema = "{}"
  storage_schema_path = "arp"
}

The error is:

╷
│ Error: error creating new TelemetryServiceRegistryEntry
│ 
│   with apstra_telemetry_service_registry_entry.x,
│   on main.tf line 46, in resource "apstra_telemetry_service_registry_entry" "x":

If I change arp to generic, this works okay. Only a handful of the validated storage_schema_path values seem to work. Is it because they're not valid, or because my (empty) application schema can't use that path?
