Hi all,

I have a regex with check match in my workflow and want to see if the string is empty.

I tried the obvious: .

But it didn't work for some reason.

I could type in [0-9a-z]  etc. but that wouldn't involve # or & or ...

I tried ..* as well but it didn't work. Ideas?

    Can you instead use "Set a condition" action which has built in comparison to see if a string is empty?

    Is there a reason you have to do this with RegEx?  You can use a Set a Condition action and check if a variable is empty, and then perform an action on it depending on the result.
