To Reproduce I have uploaded a sample project.

The crash occurs whenever a message is posted from the main thread to the worker outside the constructor. It is interesting that this does not replicate when posting from the constructor, but at a later date.

I have slightly modified the demo from worker-loader to reproduce the issue when tapping the button.

Expected behavior Application should not crash and worker onMessage method should execute to completion.

@silviudeacyour test application is working as expected on my side - no crash and the worker is doing its job when executed. Is the issue happening on a specific device/API level (I've tested on emulator API28) ?

I tried replicating by running from CLI and to my surprise it does not replicate:

tns run android

The crash happens only when running using Visual Studio Code by using the 'Launch on Android' configuration:

        {
            "name": "Launch on Android",
            "type": "nativescript",
            "request": "launch",
            "platform": "android",
            "appRoot": "${workspaceRoot}/demo-angular",
            "sourceMaps": true,
            "watch": true
        },

Alternatively I have also replicated this by running from CLI and attaching the Visual Studio Code debugger afterwards, so it is somehow related to that though interestingly happening only on Android.

@silviudeac ok it seems that debugging a worker is broken - thanks for reporting that one.

Moving the issue to the VScode repo.

NickIliev avatar Aug 23 '19 12:08 NickIliev

I am facing the same issue. My app i using workers. I can't debug it with VSCode
