no what text is in the $Verbatim$ column (as well as the type of it - I guess string?)
Or at least one string or example where i can get the error myself
the regex looks fine so it should be something about the rest
ok i found your problem.
You miswrote the regexreplace function.
It should be “regexReplace” intead of “regexreplace”
*also the correct regex would be (regex is correct but the \ have to be escaped - i think the string replace node does not need that)
[\\’\.\\w-]+@(?:[\\w-]+\.)+[a-zA-Z]{2,4} <-just noticed that the forum also thinks \ is the escape character - so maybe you already had the correct one :))
I think the color already tells you that something is wrong (not that it is stated somewhere :
