Livesync and debug mode stops after JS error

[tsonevn]

@AhmedAzzabi commented on Sat Nov 10 2018

So I was testing with version 5.0, I noticed that if I have small js error like undefined or null reference exception the debug mode stops, emulator shuts down and looks livesync, which slows my workflow as everytime I have to relaunch emulator and debug also adb.exe process stay hanged their and I need to kill it from task manager in order to reboot properly otherwise debug active but emulator gebynotion does not show like running in background.

Hi @AhmedAzzabi,
I tested the described case, however, was unable to recreate the problem. The project was successfully synced after fixing the error which was causing the problem. Regarding that can you provide some more info about your environment(CLI, tns-android, tns-core-modules, node, versions) as well as some steps to reproduce? Also, does this problem happen only on emulator?

Hi @tsonevn the issue is still reproducible, take the sample app that have Tap counter, in onTap click for example put some code that will cause error in JS like "let x= y.z" and y is null this normally will crash the app, you will notice that after the crash the debug mode with VScode is not active anymore and if you used the VScode to launch the debugger with F5 it will close the emulator too.
