Regex replace function in String manipulation and string replacer [\.\&\@\-\_\(\)\{\}\[\]\'\"\;\:\,\%\*\/\\\#\+\=\^\>\<]

While using Regex “[.&@-_(){}'";:,%*/\#+=^><]” to replace special characters, String Manipulation node is giving missing value and string replacer node is giving desired result

Please tell me why this is happening

Regex replacement as you described works for me in the String Manipulation Node. I’m using the following expression:

regexReplace($column1$, "[.&@-_(){}'\";:,%*/\#+=^><]", "")

Did you make sure to escape the double quotes in the expression?

If so and you’re still running into the problem, could you provide me with a small sample workflow that shows the erroneous behavior?
