I don’t like that “callback popup”; instead, I’d like to have them on my IDE.
… and/or, hopefully e.g. pudb also could be allowed to debug.
If you set debug to false, the errors will be routed to the console.
… but then can my IDE intercept the exception? 
Hello @stdedos,
The only way that I know of to catch errors is to wrap it in try except clauses.
I believe that there may be some work a better error handling, but I am not 100%.
You might be able to leverage something like this if you want to:
I want to run a simple repl/debugging session.
If that would be a “plain python script”, then any extension would crash the program. I understand that, in a server, not every malformed request can crash the server; instead “its processing thread dies”
Sentry is so far out of where I am 
Hmm, you can also do a self hosted version of Sentry if you want to take a stab:
Printing to the IDE console works until you are in production, at that point it becomes a lot harder to capture the errors.
