Hi,
I have a regex(abc=(.*?)).findSaveas(cor_abc),
if I run script for user1 it will find the value and saves in cor_abc, for user2 it does not find the value. in this case how to send any default value for user2?

Please advise

You can use transformOption: https://gatling.io/docs/gatling/reference/current/http/check/#transforming

regex(abc=(.*?)).transform {

case None => SOME_DEFAULT_VALUE
case some => some
}.saveas(cor_abc),

Indeed, it would be nice to have a built-in.

Implementing this built-in would be an easy contribution: https://github.com/gatling/gatling/issues/4114
