Error: Call to a member function load() on null in Drupal\media_taxonomy_filter\Plugin\views\argument\IndexTidMediaDepth->title()

Problem/Motivation

Error: Call to a member function load() on null in Drupal\media_taxonomy_filter\Plugin\views\argument\IndexTidMediaDepth->title() is thrown after updating the module to 3.0.0-beta1 on Drupal 10.3.1.

This seems to be caused by the following line of code.

$term = $this->termStorage->load($this->argument);

Debugging $this->termStorage results in a null object.

Steps to reproduce

1. Create a view page display with the following contextual filter: Media: Media has taxonomy term ID (with depth)
2. Loading the page results in a a 500 error

Proposed resolution

Change:

$term = $this->termStorage->load($this->argument);

to use Drupal::entityTypeManager():

$term = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->load($this->argument);

Remaining tasks

1. Create a MR with the proposed resolution
2. Test the change
