Canvas Packaging: Any change to app yaml file causes parsing error

[MichaelJata]

Hi,
whenever I make any changes to e.g. App.fx.yaml, I get the following error when trying to pack it into a msapp:
pac canvas pack --msapp Naacda530-e381-4650-82bc-2d6099c37a17-document.msapp --sources .\MSAPP-Content\
PA3003: Parse error: Property should be at same indent level

As an example, in the OnStart event, I am setting up some Branding Colors and changed the variable from "Black: ColorValue("#00000")" to "Black: ColorValue("#000000")". So just added "0" to the color value which works when changing in the App Studio.

After saving and executing the canvas pack, I am facing the mentioned error.
Just packing the package after unpacking (and without any modifications) works.

I am using Version: 1.29.11+g9e2b163

Any ideas about what is going wrong here?
