Decode secret is not a valid cert\/public key

[waynercheung]

Hi, I've got the "Decode secret is not a valid cert/public key" error.
This is my code:

print("========")
local jwt = require "jwt"
local cjson = require("cjson")

local jwt_token = "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImlhdCI6MTUxNjIzOTAyMn0.OfyWHrVEyPY4JdL5FqWVKdn3Q3tz52Hsd2QK7FLl65hYnO-15bc32ceZTRqbUgLsSnn0nH-hrxM4Es49IFUG6b6eAXMNCAeOiWxtFjuzOVqymx9zwYgHYT4Psk0Furyg6kJFqR5RcYazHkzBL2sbKAQkBp1ln5so3v4YCC4zcI2FaLlvo_jxeJmgQIYZ5amGurzZFvBm_jLrALqzFuXG_YRgUl5_qPGYWThl0rrfdWeqG415uuEstEEjirIPY4j5nfMPJmnsNCpJ0Pm3JMQMazJTL2Uo0sOS-M_NAXzIyNF-53NS0gsswtB5FianU_IRWv4Jm3gr4yghoGIx9_oG2g"

ngx.say(cjson.encode(jwt_obj))
return ngx.exit(200)

Is there any wrong with my code ?

You should add -----BEGIN PUBLIC KEY-----<token>\n-----END PUBLIC KEY-----
This work for me
