When I try to configure the string manipulation node to trim my variable NIS code by using the command substr(…,…,…), I get the following error message:
Could someone explain to me how to solve this? When I first configured this node and executed it, there were no errors. When loading this workflow again, I got this error.
Could you provide the String you are using in your variable? Or give an example workflow?
Just with the error message I cannot actually see what is wrong
I’ve updated KNIME and now it works fine. Must be some kind of bug which has been resolved with the update… Still, thanks for your response!
