Upon running `electron-forge make` on target `dmg` TypeError: Cannot read property 'call' of undefined

Please describe your issue: After successfully packaging, and testing my app, I run electron-forge make for target dmg and I get the error found below. My question is, are these commonly errors in my own code-base or is this something with electron package?

*Console output when you run electron-forge with the environment variable `DEBUG=electron-forge:`. (Instructions on how to do so here). Please include the stack trace if one exists.**

So I've updated my issue because it only seems to be affecting the dmg make target.

[MarshallOfSound]

@joshuairl What version of electron-forge is this?

EDIT: Of note in the stack trace it looks like a promise was rejected _promiseRejected and from a cursory inspection of the transpiled code the .call is pushing the error onto the promise context (not our code).

[jfrux]

Sorry! Appears to be electron-forge@3.0.0?

[MarshallOfSound]

@joshuairl I don't see it changing too much but can you update to latest. (3.0.1)

[jfrux]

So it's definitely happening because of a "file not found" error on background or icon property in electronInstallerDMG. It's just not showing file not found, or anything of the sorts. It appears to be getting snuffed by a try / catch somewhere.

But it's not a very descriptive error message so took me a bit to debug.

I can try updating to 3.0.1, but it doesn't appear to affect this issue.

[jfrux]

When I fixed the paths, it works now.

[MarshallOfSound]

Yeah, that was what I was inferring this edit 👍

EDIT: Of note in the stack trace it looks like a promise was rejected _promiseRejected and from a cursory inspection of the transpiled code the .call is pushing the error onto the promise context (not our code).

Looks like a bug in one of our babel transpilers, I will try to repro and follow up with them but async/await transpilation might be beyond me 😆

[MarshallOfSound]

Closing this out for now as it's an upstream babel transpilation issue that afaics has already been fixed (just needed a clean release 😆 )
