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

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project follows, as appropriate.
• I have searched the issue tracker for an issue that matches the one I want to file, without success.

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.

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 😆

When I fixed the paths, it works now.
