User storage not persisting

问题

I am trying to keep a hold on values grabbed during the conversation and make it available on the next conversations on the flow using user storage. However I see empty user storage on my next intent. Can someone please advise?

  function askAccountNumber(agent){

      var number = agent.parameters.account_number;   

      let conv = agent.conv();      
      conv.user.storage.account_number = number;                  

      agent.add('Great, your account number is ' + tmp);      
      agent.add('Welcome to the Enacomm banking application. What would you like to do?')      
  }


function askService(agent){

    let conv = agent.conv();
    agent.add(JSON.stringify(conv.user.storage));    //THIS IS BLANK {}      

    var service_type = agent.parameters.service_type; 
    agent.add('Good! You asked for ' + service_type);    
  }

This is an open issue on the dialogflow-fulfillment-nodejs library.

I changed my library from dialogflow-fulfillment-nodejs to actions-on-google-nodejs and it worked like a charm.
