Mismatch in types between electron-installer-snap and electron-forge, Error code 2

[tvvignesh]

Hi. In maker-snap according to electron-installer-snap configs documented here (https://github.com/electron-userland/electron-installer-snap/blob/master/docs/api.md) appConfig is an object but according to the types documented in electron-forge here (https://js.electronforge.io/maker/snap/interfaces/makersnapconfig) it is declared as a String.

Also, I am getting this error both with and without core18 in appConfig.

This is how I have set my snap forge config

{
	name: '@electron-forge/maker-snap',
	config: {
		name: 'myapp',
		version: '1.0.0',
		appConfig: {base: 'core18'},
		features: {
			audio: true,
			mpris: 'com.myapp.www',
			webgl: true
		},
		summary: 'My App Summary',
		description:
			'My App description',
		grade: 'stable'
	}
}

I am using "@electron-forge/maker-snap": "^6.0.0-beta.50", added to my dev dependencies which used to work before (I did an update and upgrade of the system yesterday, Not sure if that is the reason)

System info:
Linux vignesh-predator 5.3.0-45-generic #37-Ubuntu SMP Thu Mar 26 20:41:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Running Ubuntu 19.10

PS: I did refer these but didn't help much (#1531 and electron-userland/electron-installer-snap#24)

Thanks.

I'm having the same issue on Ubuntu 20.04! .DEB builds fine, but SNAP has an issue.

{
          "name": "@electron-forge/maker-snap",

          }
        }
