No data in Excel reader causing nodes to fail

KNIME Analytics Platform

Hi Everyone!

I am new to the knime community and started working on knime recently. Few days back I created knime workflow which was working fine. however a data set from one of the multiple excel reader was not consistently available which was causing the nodes to fail.

I have already tried empty table switch but it’s not working as data is completely not available from source, and now I want to bypass the joiner node which connects this data to other major ones, is there a way?

Hey there and welcome to the forum,

your thought process to tackle the problem already leads you in the right direction!

Empty Table Switch helps you in case an empty table is returned (this gives you only a node warning, not a node error).

The moment you deal with errors you want to work with Try and Catch nodes.

Feel free to share some example data here and I’m sure we can help you out.

If you want to tackle it yourself I recommend watching this video about try-catch set ups:
