Service Fabric error: “Service does not exist”

Question

I am getting error FabricServiceNotFoundException: Service does not exist. and I can't figure out why. The service name I am creating is exactly what it is deployed in my cluster.

This is the code where I create my service:

return ServiceProxy.Create<ICheckoutService>(
                new Uri("fabric:/ECommerce/ECommerce.CheckoutService"),
                new ServicePartitionKey(0));

This is the explorer view. The name of the service matches my code. I'm doing it with other services with no problem.

I tried a complete restart but I got the same error:

1. Deleted application from the cluster
2. Unprovisioned type from the cluster
3. Restarted the cluster
4. Restarted Visual Studio
5. Rebuild and deployed application

Update

After testing around I found out that the error occurs depending on the order on which I call services through my API methods.

If I deploy the application and call methods checkout and get basket they give "Service not found" error.

However, if I call other methods first that perform some change (POST), then it works... weird right? This is my repo to help take a look at the code.

With help of @maf748 I turned on "Break When Thrown" configuration for all CLR exceptions, and I discovered that the actual exception was not "Service does not exist".

In my case, I left the following auto-generated method for an Actor service, which was setting my state in a wrong state, and it was later failing in my own code.

All I needed to do was to remove this method that Visual Studio created from my method and it worked properly.

    /// <summary>
    /// This method is called whenever an actor is activated.
    /// An actor is activated the first time any of its methods are invoked.
    /// </summary>
    protected override Task OnActivateAsync()
    {
        ActorEventSource.Current.ActorMessage(this, "Actor activated.");

        // The StateManager is this actor's private state store.
        // Data stored in the StateManager will be replicated for high-availability for actors that use volatile or persisted state storage.
        // Any serializable object can be saved in the StateManager.
        // For more information, see https://aka.ms/servicefabricactorsstateserialization

        return this.StateManager.TryAddStateAsync("count", 0);
    }
