🎉🪄 LGTM - some thoughts - does this require any command helper update or az-cli impact? It also seems some build is failing as part of commit checks, thanks heaps.

I know that some of the unit tests had to add the BUILDCONTEXTPATH to their flagValuesMap or else they'd fail due to the prompt for the build context appearing with no way to input. If a test or something like that runs into a similar situation for either of those then I could see it impacting it. Otherwise, it shouldn't affect them at all!
