Follow belos steps

  1. Assign “” to the strVar1 in default value
  2. Then check condition like this String.IsNullOrEmpty(strVar1.Trim)

It will work

give a try on following condition:

isNothing(yourStringVar) OrElse String.IsNullOrWhitespace(YourStringVar.Trim)

it will return true in case of the string doesnt have a value
