Youtube-tui does panic if invidious has popular feed disable:

thread 'main' panicked at 'index out of bounds: the len is 0 but the index is 0', src/items/itemlist.rs:42:16

Fix

In commands.yml, change launch_command to something else (for example loadpage watchhistory ;; flush ;; history clear).

What happened

I believe when you disable the popular feed, instead of returning nothing on the api request, it returns an empty array (instead of an error) which itemlist sorta freaks out.

The Popular item in pages.yml is just the popular page button, by all it does is load a page (similar to a hyperlink). But because in the launch command in commands.yml loads the popular page on start, as soon as the page loads it crashes because it was not expected to recieve an empty array.

I'm gonna catch this case so it doesnt crash maybe later

Invidious returns a different json with status 500 if popular is disable.

{"error":"Closed stream"}

It would possible a good idea to check the status code with the .error_for_status() function.

Apparently it was already fixed a few git commits ago, its just that the latest crates.io version (0.6.2) is not new enough to include this fix, but it will be included in the next crates.io version

this is the current behavior:
