We have a synonyms processor that works only on Meilisearch backends. When using an index connected to Meilisearch backend we can enable this processor. However when this processor is enabled and we edit the index and disconnect it (or use another backend), visiting "Processors" tab throws the following error.
Error: Call to a member function getBackend() on null in Drupal\search_api_meilisearch\Plugin\search_api\processor\Synonyms::supportsIndex() (line 145 of modules/contrib/search_api_meilisearch/src/Plugin/search_api/processor/Synonyms.php).
