"Encountered duplicate row ID ..." error in Generic Webservice Client

KNIME Analytics Platform
#1

I am trying to process a bunch of database records through a WS Client. The records are retrieved by the Database Connection Reader, and I can view them in the Interactive Table node. The records are distinct, there are no duplicates in the set, but the WS node fails after 3% throwing the following error:

ERROR Generic Webservice Client Execute failed: Encountered duplicate row ID "Row452" at row number 465

I tried to search an answer on this Forum, but no luck so far. I would appreciate any advice on what may cause this issue, and how to fix it.

I know this is an old post, but a documentation of a solution certainly makes sense. :slight_smile:

A suffix for the RowID must be specified in the node configuration under “Advanced”. That´s it. :):blush:
