Trouble with codesigning NW.js app for MacOS - code-signing

Question

NWJS Version : 0.28.0
Operating System : MacOS 10.13.3
Here is a fragment of bash script that I use for codesign:
export IDENTITY=YFXXXXXXXX
export PARENT_PLIST=./certs/parent.plist
export CHILD_PLIST=./certs/child.plist
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Helper.app
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Framework.framework/Versions/A/Resources/app_mode_loader.app
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Framework.framework/Versions/A/XPCServices/AlertNotificationService.xpc
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Framework.framework/Versions/A/Helpers/crashpad_handler
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Framework.framework/Versions/A/nwjs\ Framework
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/nwjs\ Framework.framework/libnode.dylib
codesign --deep -s $IDENTITY --entitlements $CHILD_PLIST $helpersPath/libffmpeg.dylib
codesign --deep -s $IDENTITY --entitlements $PARENT_PLIST $APP_PATH
chmod -R 777 $APP_PATH
cd $APP_DIR && productbuild --component "$APP_NAME.app" /Applications --sign $IDENTITY "$APP_NAME.pkg"
I signed everything that Application Loader and ITunesConnect asked for. I had a lot of issues before while uploading a package. It all has been solved by codesigning everything. Now the package can be uploaded. However, I can't run .app after codesign. Before codesign it works good.
Here is also child and parent plists.
Child:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.inherit</key>
<true/>
</dict>
</plist>
Parent:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.network.client</key>
<true/>
</dict>
</plist>
