AMBOSS Add on does not work

Hello-unable to select “Easy” on the bottom of the Anki card when I’m flipping through. Getting a notification each time I try to use my AMBOSS add-on. Please see below.

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 on the add-on support site.

Thank you!

This seems to be caused by a bunch of add-ons. Follow the instructions provided in the error message.

Based on the error message, it looks like the issue originates in the load balancer add-on. All other add-ons mentioned in the error message are just “bystanders”.

I would suggest creating a new bug report on load balancer’s official bug tracker, mentioning the exact steps that reliably produce this error for you and attaching the error message:
