Text fallback not working with parameters

Am I wrong or does the text fallback have a bug…
Using dynamic value for a text (h2 in this case) that reads a url parameter… I’d think that if the URL param is undefined/falsy the faallback value would kick in and it’s not… neither within the studio, nor the client side

this IS working, but this is doing some fallback on the dynamic value itself so makes me wonder what’s the Fallback field for

Good question, fallback only applies if there is an error evaluating the expression, specifically a typeerror. You can do what you are showing if you want to have a default value that applies even if the expression evaluates successfully but evaluates to empty

ok, thats good to know! I’d say that could be a tooltip info icon next to the fallback label so it’s more clear! thanks!!
