Database Reader error StringCell and does not comply with its supposed superclass BinaryObjectDataCell

Hi

I have configured the Database Reader node to connect to a SQL database but am getting the following error

ERROR Database Reader Execute failed: Runtime class of object "" (index 14) in row "Row1" is StringCell and does not comply with its supposed superclass BinaryObjectDataCell

I am using v2.9.4 and my colleague has the most recent v2.10.1 and his node connects without an error.

Any ideas please?

thanks

Gayle

I've worde it out - it was the blank data in a variable that was causing the error - this must have been fixed in the latest version :-)
