KeyError: 'wikidata'

This is the error that I get when I run my SearxNG instance with wikidata engine enabled, and then search something.
I use https://github.com/searxng/searxng-docker, basically vanilla, with a few tweaks to settings.yml.
When I try to search with WikiData enable this is what gets displayed in the browser.

Best regards,

Nevermind, the issue was useragent_suffix in outgoing. I am so sorry, I only realized this obvious error, after posting it. Best regards.

basically vanilla, with a few tweaks to settings.yml.

The issue is not reproducible with defaults, so I guess the issue is related to your "tweaks" in settings.yml

Good point, I will try with original config, and get back to you.

You are right, the original config does not have this issue.
This is my current config (with comments removed):

From my point of view, there is nothing in this config that should cause SearXNG to simply decline to work, and I believe that this should be investigated as an issue, but still, you are completely right that it is what causes the issue. When I find time, I will try to debug it myself, and will get back to you.

The issue was useragent_suffix in outgoing in settings.yml.
It is not a good idea to set it to anything you want it to be.
