SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry

Question

Can any one help me with this? I'm not sure what's causing my feeds importer to fail on import.

I have debugged the saving function of the feed item found out it's trying to insert the node twice but not sure how to get around it or fix it so i don't run into the issue.

Throwed exception:

PDOException: SQLSTATE[23000]:
  Integrity constraint violation:
    1062 Duplicate entry 'node-284' for key 'PRIMARY':
      INSERT INTO
        {feeds_item} (entity_type, entity_id, id, feed_nid, imported, url, guid, hash)
      VALUES (
        :db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2,
        :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5,
        :db_insert_placeholder_6, :db_insert_placeholder_7
      );
