Oh, right, did you set this? AshJsonApi.Resource — ash_json_api v1.7.0
i.e query_params: [:start_date, :method]. I’m trying to remember why we require that to be set 
… I think it is for post and other methods that could include a body and so require being told what is where. In the future we could probably assume that for get requests all of the inputs are query params.
