Cannot set property 'socket' of null

[tsonevn]

From @RoyiNamir on August 12, 2018 9:42

After upgrading our project to 4.2 , we've experiencing socket connections problems to a real device when tns run android

Worth to mention that tns run android does work with emulators ( both Geny & AVD) , but it doesn't work with real devices ( my Galaxy s8+ and a colleague's Galaxy s8 , non rooted regular device)

C:\projects-web-storm\digital\dsapp1>tns info
√ Getting NativeScript components versions information...
√ Component nativescript has 4.2.1 version and is up to date.
√ Component tns-core-modules has 4.2.0 version and is up to date.
√ Component tns-android has 4.2.0 version and is up to date.
× Component tns-ios is not installed.

When tns run android :

we get :

Unable to apply changes on device: ce031713a8d0149e0d. Error is: Socket connection timeouted..

--> Video showing the problem <--

The app IS installed but not invoked. ( it used to work) before upgrade.
We have to tap the launch icon in order to see the app running
PackageID is the same in all files ( manifest / packagejson)

BTW - if you want a real project that produces it , I can send privately.

Windows machine , Android , Antivirus & firewall is disabled , uninstalled App from device.

Hi @iguissouma,

Can you please specify device model and Android version of the device?

I'm to, on Android 4.4.2 (real device), but after re-run app works.

[tsonevn]

Hi @RoyiNamir,
Can you try to clear the npm cache via npm cache clear delete platforms, node_modules, hooks folders and package-lock.json file? Uninstall the app from the device and rebuild it with tns run android command.

Hi @tsonevn
Sure.

Here is the folder after delete ( created a new folder named tsonevn):

run npm i

The current project contains a webpack.config.js file located at C:\projects-web-storm\digital\r\tsonevn\webpack.config.js that differs from the one in the new version of the nativescript-dev-webpack plugin located at C:\projects-web-storm\digital\r\tsonevn\node_modules\nativescript-dev-webpack\templates\webpack.angular.js. Some of the plugin features may not work as expected until you manually update the webpack.config.js file or automatically update it using "./node_modules/.bin/update-ns-webpack --configs" command.
Dev dependency: @angular/compiler-cli already added. Leaving version: ~6.1.0-beta.1

NativeScript Webpack plugin was successfully added.
You can now bundle your project by passing --bundle flag to NativeScript CLI commands:
    - tns build android --bundle
    - tns build ios --bundle
    - tns run android --bundle
    - tns run ios --bundle
You can also pass the "--env.uglify" flag to use UglifyJS for minification.

@Fatme @tsonevn I am still seeing this with 4.2.2
The first run works. But then if I run it again it fails.
In my logcat I keep on seeing this:
failed to connect to socket 'localabstract:org.nativescript.apps-livesync': Connection refused

I am getting this almost all the time :s I can't even update my apps.
Happening on emulator and device

[RoyiNamir]

@farfromrefug remove the dash from :org.nativescript.apps-livesync and make a capital letter in org.nativescript.Appslivesync

See this

#3819 (comment)

[farfromrefug]

@RoyiNamir and where should I do that. I can't This I not the app name! The app name is simply org.nativescript.apps
I guess the -livesync is added by the CLI
