Error when launching a cloud deployment when a Linux client isn't built.

We are accepting issues and we want your feedback.

Issue

As of release 0.6.0, you may get the following type of error when running a cloud deployment:
Could not download workers: could not download Artifact(UnrealSimulatedPlayer@Linux.zip) for Worker(SimulatedPlayerCoordinator); could not retrieve artifact information for UnrealSimulatedPlayer@Linux.zip: rpc error: code = NotFound desc = Artifact(UnrealSimulatedPlayer@Linux.zip) of Assembly(offloading_workflow) of Project(demo) doesn't exist.

This happens because SpatialOS expects the worker package that corresponds to every worker config. In this case, Simulated Player binaries are missing.

Workaround

We have two potential workarounds:

1. Build a Linux client and upload it as part of the assembly. See https://github.com/improbableio/UnrealEngine/blob/4.22-SpatialOSUnrealGDK-0.6.0-rc/Templates/TP_SpatialGDK/spatial-resources/BuildProject.bat for a reference script. This is the recommended approach.
2. Remove spatial/workers/improbable/spatialos.SimulatedPlayerCoordinator.worker.json and re-run spatial build build-config to remove the SimulatedPlayerCoordinator bridge config and descriptor from the assembly and re-upload. With this approach Simulated Players will not work.
