@Tabs13 how is req.body being populated? I suspect that you probably have some middleware or parser doing something to the request body which is altering it from it's raw state. Can you share more code?

Still waiting on feedback, I can't help you debug this without more information. I'm under the impression this is an error on how the request body is being passed to alexa-verifier
