I’m trying to follow this tutorial (Tutorial: How to Create DMN Models and Combine Them with BPMN (Video 6) - YouTube) but receiving this error. Somebody may help me?

You need to add quotes around the output strings - i’ve added them here.
Sorry about that, i understand that the error message is not very helpful.

Niall, thanks. I promise that I’ll pay attention next time.

But, sorry for ignorance … Why do we need to add quotes every time? It should be the default.

It’s because the FEEL notation requires it as part of the standard.

I’ll study more about it. Thanks.
