node to traverse cannot be null (Hibernate SQL)

Question

I\'m performing a SQL query through hibernate, which looks like:

SELECT thi 
FROM track_history_items thi 
JOIN artists art 
  ON thi.artist_id = art.id 
WHERE t         


        

Answer 1

This error comes usually due to one of the most stupid reason that one would not have even imagined. If you dop copy-paste the query, some special characters get introduced and you start getting this error. Make sure you type the query manually and it will work fine. Atleast in my case it worked.
