Hi,
How do you debug something like this where the only reference is my test class and it does not say which class it failed injection on?
com.google.inject.CreationException: Unable to create injector, see the following errors:
1) Could not find a suitable constructor in com.lightbend.lagom.internal.javadsl.server.ResolvedServices. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.

My setup code looks like this
@Before
@SuppressWarnings("unchecked")
public void setup() {
mockPersistentEntityRegistry = mock(PersistentEntityRegistry.class);
mockEntityRef = mock(PersistentEntityRef.class);
scheduler = mock(Scheduler.class);
when(mockPersistentEntityRegistry.refFor(MyEntity.class, "expectedEntityKey"))
.thenReturn(mockEntityRef);
Setup setup = defaultSetup()
.withCassandra(true)
.configureBuilder(builder ->
builder.overrides(
bind(MyService1.class).to(MyService1Stub.class),
bind(MyService2.class).to(MyService2Stub.class),
bind(PersistentEntityRegistry.class).toInstance(mockPersistentEntityRegistry),
bind(Scheduler.class).toInstance(scheduler)
));
server = startServer(setup);
}
Thanks,
Franz
