Running a query of the following format causes a NullPointerException :
SELECT col1, col2, col3
FROM TeiidView1
WHERE col2 = 'value'
GROUP BY col1
ORDER BY NVL(col3, 0) DESC
If adding adding a limit at the end of the query, it runs successfully. Similarly, removing the `NVL` function also results in the query returning results without any errors.
This is the stack trace:
