> The following java.lang.NullPointerException is received in ER7 when running queries involving lookup...example query:  SELECT IntKey, lookup('BQT1.MediumA', 'StringKey', 'IntKey', IntKey) AS Y FROM BQT1.MediumA ORDER BY IntKey
> This seems to only happen when running the production profile.  I am getting 57 query failures on most if not all sources and the queries involve lookup.
