I ran into issue when trying to pull the param value using a local variable. It throws an error about expected STRING expression on the last line due to subfield function is not prefixed with the std. namespace. Is that another way to solve this? Thanks!

 

declare local var.param STRING;

....

set var.param = "something"; // a computed variable from upstream 

set var.value = subfield(req.url.qs, var.param, "&");

  Unfortunately currently you can't do that, as the function expects a string literal, not a string variable. As this might be useful, I've passed this to our engineering team.
