I am deploying my SWOrchestration Microservice as Knative/ScaleToZero and it includes a Async Call, which it has to wait for before the Orchestration is considered complete.

While waiting for this Async call, the SWOrch is scaled to Zero. For it to re-scale to 1 and resume the workflow instance upon reciept of the Async Call, I need to setup Data Persistence to store and retrieve the Workflow Process Instance ID.

I have modified the Callback Example in my fork and branch so that the Async Call can be returned/triggered by Me manually. This works as desired.

Next: I am trying to add in Data Persistence via Mongo DB but am failing to make it work. I have so far:

Added the Pom Dependency
Added in the Application Properties to my MongoDB Server

Running

mvn clean compile quarkus:dev

I hit the error:

2021-11-30 14:06:37,364 ERROR [io.qua.dep.dev.IsolatedDevModeMain] (main) Failed to start quarkus: java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors

...

Which suggests that the Required proto is failed to being generated, meaning that the MongoDB is not storing my Process Instance.
