Putting this here means that this warning will always be printed because the outdir is expected to be created further down (in the await shell call).

I understand where your coming from with having synth not fail in this case (because manifests were actually created). However, from the CLIs perspective, synthesis is not only creating manifests, there are additional CLI features (like validations) that rely on the fact this directory exists, and so from its POV, synthesis is not successful. This does unfortunately mean that, if you define outdir in your app, you must also change the output property in the cdk8s.yaml configuration file.

Note that if you do it the other way around, i.e set output: out in cdk8s.yaml, and leave the App instance with its defaults, everything will work as expected.

I don't think this necessary though. If we found manifests, then we print their path already, indicating a successful synthesis.
