Deprecated function: str_replace(): Passing null to parameter #2 ($replace) of type array|string is deprecated

Problem/Motivation

I'm seeing the following when viewing a certain view page on my site:

Deprecated function: str_replace(): Passing null to parameter #2 ($replace) of type array|string is deprecated in Drupal\views\Plugin\views\argument\Formula->getFormula() (line 36 of core/modules/views/src/Plugin/views/argument/Formula.php).

Steps to reproduce

The site's on php 8.1 (and right now on core 9.5.11, though ran into this while prepping it for D10), and metatag should probably be upgraded 2.x, but I'm currently apparently stuck on 1.x until maybe after I can deploy an upgrade to lightning_core to get it to its next major version. But then again, line 27 of metatag_views.module (which I assume is part of the cause?) looks the same on the 2.0.x branch, so maybe this would persist.

My apologies if this isn't quite enough info to help, as I'm not super familiar with the site, this view, how metatag is configured on it, etc., quite yet (let alone the workings of how metatag is interacting with core, etc.).
