The build executable fails because it tries to load wrong "Helper.app" link

• 10.15.1:

• OSX dmg:

When I mention productName="MYAPP" in my package.json file, the resulting executable <MYAPP>.app/Contents/MacOS/<MYAPP> fails to execute giving the stack trace

There was an error parsing the Info.plist for the bundle at URL <0x7f8068400a00>: NSCocoaErrorDomain - 3840

When I inspected the code of electron-builder and checked some of the generated files, I guessed what the problem was. I think the executable is trying to execute Electron Helper.app, but when I look into Electron.app/Contents/Frameworks, I see

MYAPP Helper EH.app
MYAPP Helper NP.app
MYAPP Helper.app

The same problem persists if I don’t explicitly mention productName in the package.json file. (I think it’s getting the MYAPP from the name property in that case).

To verify that this is the issue, I rebuilt with productName="Electron" so that it will name the Helper files to what the other part of code expects. And it started working.

I believe that in past I was able to build for OSX successfully at least once (may be a 10.14.* version); but I can’t be sure. So I’m puzzled why this problem has started showing now.

The workaround of naming productName="Electron" is not really acceptable. Do you have any suggestions?

@jay3sh Thanks for sample project, reproduced. name is missed in your file association. Now it is optional and defaults to ext.

Ok, it seems when I add fileAssociations entry in my build options this problem occurs.

    "fileAssociations" : {
      "ext" : "ztr",
      "role" : "Editor"
    }

I’ve managed to reproduce it using electron-quick-start example. See if you can reproduce it on your setup.
