tns run android not working

[Volterra90]

Hi!

I'm trying to build a new app with nativescript, but I can't do it properly.

I have installed nativescript versión 7.21 and the new node LTS version 14.16.0 in my machine.

First, I run tns create and choose the Hello World template, and the project builds correctly.

Next I run tns run android --bundle, and the app is installed in the emulator I'm opening with Android Studio, but when I open the app, the app crashes with the next error:

An uncaught Exception occurred on "main" thread.
Unable to create application com.tns.NativeScriptApplication: com.tns.NativeScriptException: Application entry point file not found. Please specify the file in package.json otherwise make sure the file index.js or bootstrap.js exists.\nIf using typescript make sure your entry point file is transpiled to javascript.

I tried building the app again, with the same result. I also tried to clean npm cache and rebuild the app, with the same result.

Let me know if you need more data to check the issue.

Thanks!

Can you please attach your package.json?

Since your post there was a major release (8.0.0) introducing webpack5, if you install the latest cli with npm i -g nativescript all of the templates should work fine.
