[BUG] Tests failing on Drupal 10.2.x; TypeError: trim(): Argument #1 ($string) must be of type string, bool given

[rosiel]

The automated tests are failing on Drupal 10.2.x (which is still unreleased, so it's not critical this passes, but RC1 is out now and release will happen sooner than later).

The error is:

There was 1 error:

1) Drupal\Tests\islandora\FunctionalJavascript\IntegerWeightTest::testIntegerWeightSelector
TypeError: trim(): Argument #1 ($string) must be of type string, bool given

I have spent half an hour diving in and can't figure out why it's pointing to IntegerWeightTest's parent::setUp() call, and why trim() doesn't appear except in phpunit's TestCase.php to do with the test's name.

I'm leaving the baton here for now. Feel free to pick it up.

This appears to no longer be an issue.
