Food preparation demo is stuck?

[mwufi]

so I'm running the demo, and I can't see food being delivered

Does it have something to do with these log lines I see?

Using Restate's introspection!

Anyways, the introspection is really cool, and here is what I see! Am I supposed to be doing something to simulate the food delivery driver?

Thanks for reporting this issue @mwufi. The runtimesetup-1 looks indeed not correct. It seems as if the driver service was not properly started. The suspended invocation you show in the second image, is awaiting a completion of a promise from the restaurant_pos container. Could you check whether it logged Order ${orderId} prepared and ready for shipping?

Which food-ordering example are you running (Java, Python, Typescript, Kotlin)? Are you using the latest main of this repository? I've tried them locally and they seem to be working for me.
