Distributed Services with Go: 'make tests' fails on testProduceConsume (code matches at this stage) page 132

@travisjeffery

As per instructions up to page 132, I have checked the code against the downloadable resources and A/B’d back and forth. Everything appears to be in good shape. At this point, it tells me to update the NewGRPCServer function and then I can run make test and everything will pass as before. Unfortunately, the tests are failing.

 make test

make: *** [test] Error 1

Check the testcase shows my code is the same as the book and repo. Any ideas?

serve_test.go:107

produce, err := client.Produce(
		ctx,
		&api.ProduceRequest{
			Record: want,
		},
	)
	require.NoError(t, err)

and server_test:34

t.Run(scenario, func(t *testing.T) {
			client,
				config,
				teardown := setupTest(t, nil)
			defer teardown()

			fn(t, client, config) // this is line 34
		})

Cheers
