Hi

I am trying to read an primitive attribute name with an string parameter.

and use that parameter in a wrangler


it works if put something into the parameter, but if it is empty I get an error message: "Syntax error, unexpected '=', expecting identifier. (30,72)"

how can I avoid it?
there is a "try" command like python, to deal with this kind of error?

Thanks

I tried to submit it on the Galley, but it says page no found when I click on "submit".

Thanks!
