I am trying to decode, JWT decode is not working well because when i tried to print the decoded_token at the console its not showing it,

i am listing my env enviroments:

AUTH_FIREBASE_PROJECT_ID=basse-e824e
FIREBASE_API_KEY=AIzaS..x-_3..Z-NU......XQE_S-Ff......k4
BASE_URL=http://localhost:8010/

now i gonna to show you how is my entire code: in this code also its about to refresh certs

class FirebaseService
    FIREBASE_CERTS_URI = 'https://www.googleapis.com/robot/v1/metadata/x509/[email protected]'
    FIREBASE_CERTS_EXPIRY = 360
    FIREBASE_ALGORITHM = 'RS256'

    @@certs = {}
    @@issuer = "https://securetoken.google.com/#{ENV['AUTH_FIREBASE_PROJECT_ID']}"

    def self.verify_id(token)
      refresh_certs
      firebase_user = nil
      # find first public key that validates this token
      @@certs.detect do |key, cert|
        public_key = cert.public_key
        decoded_token = JWT.decode(
          token,
          public_key,
          !public_key.nil?,
          { algorithm: FIREBASE_ALGORITHM, kid: key, iss: @@issuer, verify_iss: true }
        )
        p decoded_token
        payload = decoded_token.first
        firebase_user = payload.select { |k, _v| %w[email name user_id email_verified].include? k }
      rescue JWT::ExpiredSignature
        Rails.logger.error 'Token signature is expired'
        return nil
      rescue JWT::InvalidIssuerError
        Rails.logger.error 'Token signature wrong issuer'
        return nil
      rescue JWT::DecodeError
        nil # go on, try the next cert
      end
      FirebaseUserVerifier.call(firebase_user:).result
    end

    def self.refresh_certs
      retrieve_certs if certs_cache_expired?
    end

    def self.retrieve_certs
      response = Faraday.get(FIREBASE_CERTS_URI)
      return unless response.status == 200

      @@certs_last_refresh = Time.zone.now
      new_certificates = JSON.parse(response.body).transform_values do |cert|
        OpenSSL::X509::Certificate.new(cert)
      end
      @@certs.merge! new_certificates
    end

    def self.certs_cache_expired?
      if defined? @@certs_last_refresh
        Time.zone.now > @@certs_last_refresh + FIREBASE_CERTS_EXPIRY
      else
        true
      end
    end
  end
