title: {"errorMessage": "Unable to unmarshal input: Expecting value: line 1 column 1 (char 0)", "errorType": "Runtime.UnmarshalError", "stackTrace": []}
body: <p>I followed <a href="https://medium.com/geekculture/deploying-pytorch-model-as-a-serverless-service-339b4b93e517" rel="nofollow noreferrer">this tutorial</a>.</p>
  <p>Steps:</p>
  <p>I downloaded <a href="https://github.com/anandsm7/BERT_as_serverless_service" rel="nofollow noreferrer">this github</a>.</p>
  <p>from where I installed the project, I executed this:</p>
  <pre><code>docker build -t logbert-lambda .
  docker run -p 8080:8080 logbert-lambda
  </code></pre>
  <p>I opened my navigator and I typed: <code>http://localhost:8080/2015-03-31/functions/function/invocations</code></p>
  <p>It gave me this error: <code>{&quot;errorMessage&quot;: &quot;Unable to unmarshal input: Expecting value: line 1 column 1 (char 0)&quot;, &quot;errorType&quot;: &quot;Runtime.UnmarshalError&quot;, &quot;stackTrace&quot;: []}</code></p>
  <p>Can't I use my navigator rather than Postman ?</p>
