python problems with input column values, missing values

Hello all,

I am using workflow to read keywords from googletrends.

Works fine so far with existing keywords, but if a keyword does not exist at google trends, then no table is created for me anymore.

What can I do? Can I set this under options? > I have already tried, but without success.

Or must that be adjusted in the script in python?

Demo_py_gtrends.knwf

Hope you can help me!

Greetings

Bernd
