Debugger hides traceback/error message and doesn't naviagate to package source when justMyCode: false

[laundmo]

Type: Bug

1. set "justMyCode": false in launch.json
2. debug a python script which causes a exception in another package
3. note how the debugger stops in my own code, and doesn't display the big red error message and traceback box like it used to

There seem to be 2 possibly related issues happening here:

1. VSCode displays the debugger as paused on the latest line in my own code.
2. VSCode doesn't display the big red box inside my code which shows the error message and traceback

Note: i can do the following steps to see the big red box of traceback for the package which raised it:

1. have the debug tab open
2. click the upper "Show More Stack Frames" line
3. click on the topmost stack frame
4. observe vscode jump to the correct file (of the package) and display the big red box with the traceback
5. the highlight for the line is green instead of yellow, showing that its not considered the "primary" line on which this exception happened.

PS: i also noticed that i'm unable to step over or continue execution on exceptions, which used to be possible (this would close the debugger with the exception being printed normally to stderr if its uncaught).

I'm facing the same issue, but in my case, it's due to a missing path:
FileNotFoundError: [Errno 2] No such file or directory: '/xxx/mambaforge/envs/pip38/lib/python38.zip'.
The issue occurs in both the native Python environment and mambaforge(conda).

This is by design. VS code doesn't show the big red box for 'hidden' frames anymore. You have to expand them manually.

Example:

This is what you'll get now for non user code.

[rchiodo]

If you expand the stack frames and double click on the top one, then you get the big red box:

[laundmo]

Would it be possible to get a setting in launch.json to re-enable this? this choice is quite annoying since most if the time the exceptions i'm debugging happen in library code.

[rchiodo]

You'd have to ask VS code for that. It's not something that debugpy can control/change.
