[RPC 008]: PUT, GET, PATCH & LIST must return the same resource schema.

PUT, GET, PATCH & LIST must return the same resource schema. Operations on a resource such as read, create, update, and list must all return the resource type itself (or a collection of the resource type for list operations).

Note

ARM RPC rule: RPC-008

Impact

• Area: API

The resource operation returns a response schema that violates the RPC contract.

LintDiff Equivalent

This rule corresponds to the LintDiff rule PutGetPatchResponseSchema (the TypeSpec rule also covers list).

❌ Incorrect

@armResourceOperations
interface FooResources {
  // Returns BarResource instead of FooResource
  @get
  @armResourceRead(FooResource)
  get(...ResourceInstanceParameters<FooResource>): ArmResponse<BarResource> | ErrorResponse;
}

✅ Correct

@armResourceOperations
interface FooResources {
  @get
  @armResourceRead(FooResource)
  get(...ResourceInstanceParameters<FooResource>): ArmResponse<FooResource> | ErrorResponse;
}

Suppression

Suppress only when required to match an existing API; otherwise use the standard operation templates and do not override the response parameter.
