Selecting rows from SQL table in scenario

How To
1

Hi
I have a scenario where I have a Microsoft SQL Server module that selects rows from a table on a SQL Server. When I execute the scenario, I get the error message:

InvalidConfigurationError
Unknown operator ‘undefined’.

The error message doesn’t specify anything else. Has anyone seen a similar issue when selecting rows from a SQL table in a scenario?

EDIT:
Selecting the rows works fine in the scenario, now I just need to turn it into a CSV file. Does anyone have an experience with this? I need to convert a bundle into a csv file.

Thanks
