Error message when trying to use widgets

Widgets don’t function in my workflows. I have KNIME 5.3.3 installed.

I am trying out what is described in this article: the How to build a custom AI-powered job finder chatbot | KNIME . The widgets don’t work at all. Tried it on earlier versions of KNIME, no luck, I get the same error messages:
