I have some custom code that uses the guess() method - changing it to guessMimeType() seems to work for me. Is this the correct solution?

Before:

$mimetype = \Drupal::service('file.mime_type.guesser')->guess($item->uri);

After:

$mimetype = \Drupal::service('file.mime_type.guesser')->guessMimeType($item->uri);
