title: Tron API works not as described in documentation
body: <p>After I run fresh Tron node with the command</p>
  <pre><code>docker run -it -p 9090:9090 --rm --name tron trontools/quickstart
  </code></pre>
  <p>I'm trying to get blocks:</p>
  <pre><code>curl -X POST  http://127.0.0.1:9090/wallet/getblockbylimitnext -d '{&quot;startNum&quot;: 1, &quot;endNum&quot;: 2}'
  </code></pre>
  <p>But instead of an array, the response contains an empty object:</p>
  <pre><code>{}
  </code></pre>
  <p>How to make node to work as it described in documentation here: <a href="https://tronprotocol.github.io/documentation-en/api/http/" rel="nofollow noreferrer">https://tronprotocol.github.io/documentation-en/api/http/</a>?</p>
