Guardian library can't able to generate the token

Question

I'm creating an API for Signup/Sign in. I'm using guardian, "~> 1.0" to generate a jwt token for my signup. Now when I create a guardian module in my folder structure which I will show you in the code. I also passed the secret key in my cofig.ex.

Let me know If you need any other information.

Now when I try to pass this in my postman endpoint it's giving me an error

{
    "user": {
        "email": "siddhant24333@gmail.com",
        "password": "Radiohead",
        "password_confirmation": "Radiohead"
    }
}

user_controller.ex

def create(conn, %{"user" => user_params}) do
    with {:ok, %User{} = user} <- Accounts.create_user(user_params),
         {:ok, token, _claims} <- Guardian.encode_and_sign(user) do
       conn |> render("jwt.json", jwt: token)
    end
end

guardian.ex

defmodule DailyployApi.Guardian do
    use Guardian, otp_app: :dailyploy_api

    def subject_for_token(user, _claims) do
      sub = to_string(user.id)
      {:ok, sub}
    end

    def subject_for_token(_, _) do
      {:error, :reason_for_error}
    end

    def resource_from_claims(claims) do
      id = claims["sub"]
      resource = DailyployApi.Accounts.get_user!(id)
      {:ok,  resource}
    end

    def resource_from_claims(_claims) do
      {:error, :reason_for_error}
    end
end

This is the error I'm getting when I try to generate the token

[error] #PID<0.554.0> running DailyployApiWeb.Endpoint (connection #PID<0.553.0>, stream id 1) terminated

Also, it's showing this

config.ex

config :dailyploy_api, DailyployApi.Guardian,
  issuer: "dailyploy_api",
  secret: "eXCQ6ZYZlPkS0p0eOoLLfkEoi0rn6O6pQ0PmhDjbElrc9G9RMQgnCMk+3kw0FHE7"

It's written that the secret is not found. Are you sure with your configurations? I'm not — Virviil, Jul 08 '19 at 12:43
Yes, I have written it in my config.ex file. I've generated the key using mix guardian.gen.secret. — Siddhant Singh, Jul 08 '19 at 13:00
I'm pretty sure from the github, that the config should have `secret_key`, not `secret` https://github.com/ueberauth/guardian#installation — Virviil, Jul 08 '19 at 13:49

Looks like a typo: rename secret to secret_key in your guardian configuration.

See https://github.com/ueberauth/guardian#installation.
