resBody VS resBodyParsed

Which one to use after a JSON response? resBody or resBodyParsed.

For me, in the JSON response the outputs[“Signin”].resBody[“refreshToken”] works but the outputs[“Signin”].resBodyParsed[“refreshToken”] doesnt work

I never use the Parsed one

The Appgyver says that " resBody should be used for backwards compatibility purposes only, this output should not be used in new apps. If you have resBody in use, please consider switching to resBodyParsed ."

But then the resBodyParsed doesnt work
