Getting an unhandled promise rejection error

Hi, I am trying to convert my electron app to appX using electron-windows-store and have been getting this error. My version of windows 10 sdk is Windows 10 SDK, version 1903.

PS C:\WINDOWS\system32> electron-windows-store --input-directory C:\Projects\Javascript\simplephotoviewer\dist\simplephotoviewer-win32-x64 --output-directory c:\projects\javascript\simplephotoviewer\dist\AppX --package-version 1.1.0.0 --package-name simplephotoviewer
You need at least Node 4.x to run this script

I am also getting this problem. My error message:

Im getting the same error. The error gives some hint as to what is going on and its because all of us are choosing "no" for the dev certificate question so it is undefined. Doing a .match on an undefined object will error out.

find you global node modules folder and go into windows-store-manager/lib/params.js

on line 86 there is a .match check for a dev certificate. Simply just check if there is a dev certificate. Im not sure if this is the actual fix however I was able to move past this error doing this fix:

if (program.devCert && program.devCert.match(/.p12$/i)) {

However this lead me to another unrelated error 🤷‍♂ The struggle goes on :D

annnnd the solution to the other problem was that my path to the windows-kits folder was wrong, its supposed to be C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64 annnnd my built package .exe file had spaces in the name "My application" which is a nono apparently. Removed the space in the package title, changed the windows kits folder to the actual one and both signing and building the .appx file worked flawlessly.

Hope this helps someone out there that runs into the same issue :D
