Build arch: universal fail macOS 12.3 TypeError: Cannot read properties of undefined (reading 'Resources')

[bjbk]

• Electron-Builder Version: 23.0.3

• Node Version: 16.13.2 [updated to 16.14.3]

• Electron Version: 17.1.2
• Electron Type (current, beta, nightly): current

• Electron Updater: 5.0.0

• Target: mac: { target: { target: 'default', arch: 'universal' } }

• Dev Machine: Mac mini (M1, 2020)

• Dev OS version: macOS Monterey 12.3

After experiencing the issue raised #6606 here, I now get the following errors trying to build.

TypeError: Cannot read properties of undefined (reading 'Resources')

UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "undefined".

I can't seem to get any further diagnosis.

EDIT:

Tried to build changing arch to arm64 - build was successful. Now to figure out how to build a universal dmg bundle. 🤔 Was even able to build win-ia32, arm64-win, and AppImage without issues.

...
mac: {
  target: {
     target: 'default',
     // arch: 'universal'
     arch: 'arm64'
  },
…

Build with x64 also successful.

...
mac: {
  target: {
     target: 'default',
     // arch: 'universal'
     arch: 'x64'
  },
…

cannot build universal dmg.

In looking at the app bundles, Contents and Resources seem to be there. So wondering what in electron/universal is not getting satisfied?
File reference https://github.com/electron-userland/electron-builder/blob/master/packages/app-builder-lib/src/macPackager.ts#L94

I really don’t want to publish 2 DMG's. Would current installs using universal auto update if I have to publish this way?

target: {
     target: 'default',
     arch: ['x64', 'arm64']
  },

[mmaietta]

Hmmm, two options were added when electron/universal was updated to the latest version:

mac: {
   mergeASARs: 
   singleArchFiles:
}

I honestly don't know what the two options do (it was a community contribution PR), but it might be worth trying mergeASARs: false?

I wish there was a stacktrace with the thrown error to help debug this. The error message is completely ambiguous :/
The promise rejected with the reason "undefined"

[bjbk]

That did it! I wonder if mergeASARs: false could be set by default. Of course that may be an issue for the electron team instead of builder.

Could the documentation mention that this prop is mandatory if using universal? I didn't get that from the docs as quoted below. Thanks @mmaietta !

mergeASARs = true Boolean - Whether to merge ASAR files for different architectures or not.
This option has no effect unless building for “universal” arch.

[mmaietta]

If this becomes a more prevalent issue, then I'll consider making it false by default. Since this is the first report of this issue, I have a feeling that it's unique to your dev env.

mergeASARS is a new param in @electron/universal, and the prop is not mandatory if using universal builds.

[mmaietta]

@andirsun did you try mergeASARS: false?

[Groxot]

Same error on Mac

 SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at /Users/electron/node_modules/app-builder-lib/src/fileTransformer.ts:41:35

and Windows

 SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at C:\electron\node_modules\app-builder-lib\src\fileTransformer.ts:41:35

when adding node_modules to build

Just chiming in to add that I also ran into this error in precisely this same scenario, and it was also resolved by setting mergeASARs to false.
