Severity: warning

This diagnostic is issued when an operation marked with @clientLocation points to a target that is not a valid client location under the root namespace decorated with @service.

Impact

• Area: Client operation placement. Generation continues, but the operation cannot be moved to a target outside the valid service client hierarchy.
• Not affected: The operation’s HTTP route and protocol metadata are unchanged.

❌ Incorrect Usage

namespace OtherNamespace {

}

@service
namespace MyService {
  @clientLocation(OtherNamespace) // target is outside the `MyService` service namespace
  op list(): void;
}

Diagnostic Message

TCGC reports:

`@clientLocation` could only move operation to the interface or namespace belong to the root namespace with `@service`.

✅ How to Fix

Move the operation to an interface or namespace that belongs to the root service namespace, or define the intended target as a valid client under that service.

@service
namespace MyService {
  namespace Operations {

  }

  @clientLocation(Operations)
  op list(): void;
}

Suppression

This diagnostic should not be suppressed. Move the operation to an interface or namespace that belongs to the root @service namespace.
