Some files are flagged as `unpack: true` in asar

[rajzik]

I am trying to package my app for mac universal and the build fails on unpacking due to misconfigured flag unpack: true for the files.

After some digging I found out that files that throws ENOENT error are flagged by unpack: true during the unpack and hence not found. For some reason xml, pem, cjs extensions are flagged as upacked even when they are not.

First off, thank you so much for a detailed issue report!

Looks like this error is coming from @electron/asar, but the unpack detection logic is indeed in electron-builder that is calling makeUniversalApp of @electron/universal

Would you be willing to put together a minimum repro repo for this so that I can quickly debug? I may need to fix a bug upstream if I can identify what's going wrong.

Can we keep this alive?

[mmaietta]

@rajzik are you still able to reproduce this on v26.3.0?

[rajzik]

@mmaietta still the same error.

[rajzik]

@mmaietta Update repro repo.

[eitambelahousky]

@mmaietta Any update on this one? Same issue on our end.

[mmaietta]

Well, I've verified my PR fixes the packaging issue, but I'm just struggling to figure out how to verify the change causes no issues with .framework file/folder/symlink structure during app runtime.
