Class Not Found error when requiring nativescript-websockets

[Dragons0458]

Hello! when I try to import the module in app.module.ts I get the following error:

java.lang.ClassNotFoundException: technology.master.nativescript.WebSocket

What could it be? Thank you!

PD: I'm using webpack and web code sharing.

Typically this means you haven't rebuild the application. Delete your platforms/android; then do a "tns platform add android" and then delete the app off the device. After you do a tns run android it should work.

Hi Nathanael, this seems to be an issue since upgrading to nativescript 5.
I have also tried your suggestion above but no joy.

Further information: tns-core-modules > 5.0.1 causes this issue. Reverting to 5.01 has solved for now.
