Jwt.io debuger debugger error when "crit"field is added in header

When i select RS256 algorithm under jwt.io , signature validation fails when i add “crit”:[“exp”] . It is working with “exp” alone without “crit” field. What is the reason ? Any help is great. Thank you

{
“typ”: “JWT”,
“alg”: “RS256”,
“exp”:1593796130,
“crit”:[“exp”]
}

Hey there!

Let me talk it over with the jwt.io maintainers and get back to you soon!

Hello any update on this?

Hey there,

Sorry for the dleay in response I got the message from JWT.io maintainers but forgot to relay it.

JWT.io uses node-jose under the hood and this is where the issue is potentially coming from.
