Debugging on multi-app layout

What’s a good way to debug an app page when I have a multi-app layout? On a single page app, I can get the errors and debug easily, but on this layout, I had to use app.config.suppress_callback_exceptions = True which removes some of the error pop-ups, so I can’t identify where the problem is at.

One way would be to use an IDE that supports interactive debugging e.g. pycharm. You can set a breakpoint in the relevant callback.
