RE: How to use pattern or wildcard responses

here is my basic chat bot

I used the sample code from above:

Pattern("* hockey *")
I love hockey, it is the best sport.

but I got error:

Pattern must end with ')' character - Pattern("* hockey *") I love hockey, it is the best sport.

here is the video showing my tests

Please explain why copying and pasting sample code from the forum/docs fails in the chat engine.

thank you
