Warning: Undefined array key "is_file" in _pathologic_replace() (line 279 of modules/contrib/pathologic/pathologic.module) after upgrade

Quickly debugging by adding following lines before that check:

  if (!isset($cached_settings['is_file'])) {
    \Drupal::messenger()->addMessage(print_r($parts, TRUE));
  }

And what was printed where simply urls, so no images.

Ok, so for some weird reason, the composer file did update the info file to alpha2, but not the module file, VERY weird. After removing and requiring again, everything is fine, sorry for the noise!

I get the same warning with composer behaving as it should but with a href="void(0); link to replace.

I get the same warning, and the PR resolved the issue

Looks like the patch fix the warning. thanks!
