LGTM.

Just wondering - imagine that we only called run_bicep_command(args) from a single place (i.e. as we do on line 3687) and just captured the output and then depending on if stdout was set we printed the value, otherwise return?

I'm wondering if that would make it less likely, going forward, for issues like this to be introduced?

Good point. I'll do some refactoring.

@shenglol Please merge this as soon as you can. This bug causes all CARML pipelines running on Ubuntu-20.04 to fail as the 'az bicep build' command does not return any more results.
The workaround of adding '--no-restore' may have other un-intended complications so we may wait for this fix to be merged.

I'd suggest using the workaround below:

az bicep restore -f main.bicep
az bicep build -f main.bicep --no-restore

Or we can just directly invoke Bicep CLI available at ~/.azure/bin/bicep.
