Anycable auth does not work on production Application error: 859: unexpected token at ''

[dmgrinko1]

Hi I have a problem on production only. On localhost everything goes ok, twith development and production mode.
Error is Application error: 859: unexpected token at ''
I have two types of request query param.
/cable?token=2bd6e874f8da05b594c1494ca25af20a
OR
/cable?device_id=CDBA1238-4FA0-4CA1-B500-9E842D186E4B
What is interesting. For device_id everything works ok, Im getting connection
Here is my def connection.rb

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    include ActionController::HttpAuthentication::Token
    identified_by :non_session_user, :uuid

    def connect
      uuid = self.uuid = SecureRandom.urlsafe_base64
      return uuid unless token || device_id
      self.non_session_user = find_verified_user
    end

    private

    def find_verified_user
      find_user_by_token ||
        find_user_by_device_id ||
        reject_unauthorized_connection
    end

    def find_user_by_token
      TokenAuth::AuthenticationToken.find(token).entity
    rescue TokenAuth::FindEntityException
      nil
    end

    def find_user_by_device_id
      User.find_by(username: "unregistered_user##{device_id}")
    end

    def token
      token_based_auth_token || request.params['token']
    end

    def device_id
      request.params['device_id']
    end

    def token_based_auth_token
      token, = token_and_options(request)
      token
    end
  end
end

Here is production log

Im not using a classic JWT token, so can`t use solution based on gem you provided
I made some tests. Looks like problem with sharing token between containers
If a create token in API container then Cable container does not know about it.
When I created token from Cable container, auth start to work. But I have to generate it from API

Problem has been fixed with setting correct redis url

[palkan]

Glad to hear that!
Was it somewhere at the authentication token side? The unexpected token at '' looks like JSON parsing error (e.g., JSON.parse(''))

[dmgrinko1]

problem was cause, token stored in redis had not been shared between applications and it was just empty string.
