Hey 👋🏻

Thank you for opening a pull request!

Could we have some test lines to add these to the test files to ensure we dont accidentally break it in future!

Hi Laurence, Thanks for quick response. Did you mean test logs? Or add this to some test folder? I created branches for all the new collections as you suggested last time.

Example log for Open-WebUI Auth error :

authenticate_user example_email
INFO: 1.2.3.4:0 - "POST /api/v1/auths/signin HTTP/1.1" 400 Bad Request

Note :
IP : 1.2.3.4

It works on the IP but I haven't managed to use this for the user enumeration as it's 2 line error log. Hope can improve on that.
