Measurement client generator does not work with C# services #851

Closed bkeryan closed 1 month ago

bkeryan commented 2 months ago

Bug Report

The generated measurement client gets a gRPC UNKNOWN error from C# services.

The generated measurement client generator does not specify MeasureRequest.configuration_parameters.type_url. C# measurement services use Any.Unpack<T>, which validates the type URL.

Repro or Code Sample

Run the C# GameOfLife example.

PS D:\dev\measurement-plugin-python\packages\generator> poetry run ni-measurement-plugin-client-generator ni.examples.GameOfLife

>>> import game_of_life_client
>>> client = game_of_life_client.GameOfLifeClient()
>>> client.measure()

Expected Behavior

It returns a measurement.

Current Behavior

>>> client.measure()

Possible Solution

Change the generator to build a type URL using the message name from the MeasurementSignature.
