400 style errors cause pop-up in Anki, return 400 or log to file, but don't break or show error pop-up

[kanjieater]

I'm running into this error with the backfill add-on (and some custom code to automate it when adding new cards.

I'm getting this error as a popup multiple times when calling the server. My request would be to treat this like a standard server 400 level error and let clients handle malformed input on their side, instead of blocking the main anki app's UI.

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you've discovered the add-on that is causing the problem, please report the issue to the add-on author.
