Getting "Aborted Orchestration accumulated output:"

Trying to run a simple Connector Orchestration connecting to an external SQL Server database sitting on the same E1 database server. Failing on the groovy statement below:

def rows = sql.rows("SELECT QMLITM, QMDSC1, QMUOM1, QMGLPT, QM_STP, QM_LNP, QMANPL, QMBUYR FROM PmmToE1Bridge.dbo.F55PMMZ1 where QMITM = 2");
