what scenario were you hitting this via?

[AezanPathan]

I ran into this on the plugins page.

When a plugin has ./agents in its config, the items do show up in the list, but clicking on them doesn’t work.

It looks like the UI is trying to fetch ./agents as a file, but since that’s actually a folder it ends up with a 404.

I also saw this in the console:
Failed to fetch ./agents

Added a screenshot for reference.

Great catch - I need to get some better validation around the website.
