Question

我从tron tron官方页面上的Quickstart with TRON Docker开始建立本地测试网。

启动tron docker快速启动成功
使用Tron-Studio成功部署智能合约
与Tron-Studio的合同成功使用

使用本教程中的代码，我可以获得合同，但是当我使用合同的功能时，承诺就会超时。

dockerstate.js：

const TronWeb = require('tronweb');
const HttpProvider = TronWeb.providers.HttpProvider;
const fullNode = new HttpProvider('http://127.0.0.1:8090');    //Your local TVM URL  
const solidityNode = new HttpProvider('http://127.0.0.1:8091');
const eventServer = 'http://127.0.0.1:8092';
const privateKey = 'da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0';

const tronWeb = new TronWeb(
    fullNode,
    solidityNode,
    eventServer,
    privateKey
);

async function changestate(){

  let contractAddress = 'TAA6PHMkrQs5bZp7cBYcfdWES9EMb5BZaK';   //Your address
  let contract = await tronWeb.contract().at(contractAddress);
  let resultPost = await contract.postMessage("TRON to the Future").send();
  let resultGet = await contract.getMessage().call();
  console.log('resultGet: ', resultGet);
}

changestate()

控制台输出：

似乎智能合约无法使用Web API正常工作。有什么建议可以解决问题，以及如何解决或调试它？

Tron智能合约Web API不适用于Docker快速入门网络
