[3.x]: Using SORT filter errors with "Nesting level too deep - recursive dependency"

Hey Anna!

Usually that error occurs only if Xdebug is enabled. Sometimes it occurs for actual infinite recursion bugs, but not always.

Can you try loading the same page with Xdebug disabled, and see if it works?

Thank you for your quick reply Brandon!

I'm seeing this error in both production and dev environments and neither have Xdebug enabled according to PHPinfo report.

This was working code that appears to have broken with the latest upgrade that I made to 3.9.13.

Assuming you are trying to sort the categories by their titles, try this:

{% for year in years|sort((a, b) => a.title <=> b.title)|reverse %}

Hi Brandon,
Thank you! This got the sorting working again.

The issue should be reproduceable with PHP 8.1.25 and Craft 3.9.13.

Glad to hear that solved it!
