osx-sign: electron app crashes after signing. Works fine without signing.

I want to make my electron application live to mac app store. So i found article and i followed this steps:

1. I used electron packager to pack the application with this command: "electron-packager . --appname=cruster --app-bundle-id=xxx.xxx.xxx --version=1.7.10 --overwrite --platform=mas --arch=x64 --icon=./app.icns --prune --out=mas-build --ignore --app-version=1.0.0"

Note: After 1st step, cruster.app is generated and when i run this .app file it opens successfully and run fine.

2)And then i am using electron-osx-sign to sign my application with given command: electron-osx-sign cruster.app --type=distribution --identity=“3rd Party Mac Developer Application: XXXXX (XXXX)” --entitlements=‘parent.plist’ --entitlements-inherit=‘child.plist’ --provisioning-profile=“distribution.provisionprofile”

Note: After 2nd step, when i open my cruster.app is crashes with error :

Exception Type: EXC_CRASH (Code Signature Invalid) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY

1. if I use system’s codesign command: codesign --deep --verbose --force --sign "3rd Party Mac Developer Application: XXXX (XXXX)" cruster.app

then it signs successfully and also opens and runs.

But after that i use below command to generate .pkg and load it to the application loader: electron-osx-flat HK.app --identity="XXXX (XXXX)" then it generates .pkg but then application loader throws error that sandbox is not enabled.

I am trying this for two days and i’m out of solution, please can anyone help?
