io.grpc.StatusRuntimeException: UNAVAILABLE: Channel shutdownNow invoked

Hi all

I have written a test class that to test the implementation of the GRPC server.
The test is pretty straightforward:

@QuarkusTest
class CertStoreGrpcTest {

    @GrpcClient("cert-desk-svc")
    lateinit var desk: CertStoreService

    @DisplayName("Create key- and truststore regarding user id")
    @Test
    fun testCreateUserCertStore() {
        println(desk)

        desk.createStore(
            CreateStoreRequest.newBuilder()
                .setStore(CertStore.newBuilder().setId("3b9553d6-2002-4485-9487-a660f23d553c")).build()
        ).subscribe().with{ println("Hello") }
    }

    @DisplayName("Get info from existing key- and truststore")
    @Test
    fun testGetUserCertStore() {

    }

    @DisplayName("Get info from none existing key- and truststore")
    @Test
    fun testGetUserCertNoneStore() {

    }

}

Running the test it shows me:

2022-06-30 22:05:25,791 ERROR [io.qua.mut.run.MutinyInfrastructure] (grpc-nio-worker-ELG-3-3) Mutiny had to drop the following exception: io.grpc.StatusRuntimeException: UNAVAILABLE: Channel shutdownNow invoked
        at io.grpc.Status.asRuntimeException(Status.java:535)
        at io.grpc.stub.ClientCalls$StreamObserverToCallListenerAdapter.onClose(ClientCalls.java:487)

What am I doing wrong?

Here is the project:
cert_desk_svc.zip

To run the test just write ./gradlew quarkusTest on the console.

Kind regards

In the application.properties file the following lines are needed to get it work in the test mode:

%test.quarkus.grpc.clients.cert-desk-svc.host=localhost
%test.quarkus.grpc.clients.cert-desk-svc.port=9001
