During an action (Execute SQL Script) which was returning some data and storing it to a Variable, for use in later steps.
The SQL script runs perfectly in SQL, however now when running the script with TOAD we get an error.
Error Message :
Value cannot be an empty collection.
Parameter name: columnReaders
WORKAROUND:
Go to Toad Options and check on the 'Read LOBs when initially fetching data' checkbox.

STATUS:
Waiting for fix in a future release of Toad Data Point.
