Steps to reproduce

Use the module under Drupal 9.

Proposed resolution

The module's file src/PPTaxonomyManager.php uses getVocabularyId() in two places. In each of those two places, use bundle() instead. So:

Change line 1630 from:

'vid' => $term->getVocabularyId(),

to:

'vid' => $term->bundle(),

Change line 1657 from:

$update_query->condition('vid', $term->getVocabularyId());

to:

$update_query->condition('vid', $term->bundle());
