Leaderboard template error at specific url

i started seeing lots of these errors in log for no reason

so i switched theme to default just for myself and it shows error too (at this specific url from log): https://www.techforum.cz/leaderboard/?custom_date_start=1720000800&custom_date_end=1720000800/ 🤔

if i enter url without any dates, it works fine 🤔

cache cleared 🤔

now i see the same problem here 🤔

The URL is invalid; if you take a look, you'll see there is a trailing / at the end.

Can I ask how you got to that URL? I can't seem to reproduce that from clicking anywhere on this site.
