title: escape Json Attribute Name
body: <p>NodeJs Lambda should return payload</p>
  <p>{
  &quot;statusCode&quot;: 200,
  &quot;body&quot;: {
  &quot;Customer_Code&quot;: &quot;CCode&quot;,
  &quot;c_type_/_customer_type&quot;: &quot;Customer Type&quot;
  }
  }</p>
  <p>Note the &quot;/&quot; in the atrribute name</p>
  <p>I cant get to escape this attribute name in Lambda
  <br>
  This works
  <code></p>
  <pre><code>exports.handler = async (event) =&gt; {
      // TODO implement
      event.ctype__customer_type = &quot;Customer Type&quot;;
      const response = {
          statusCode: 200,
          body: event,
      };
      return response;
  };
  </code></pre>
  </code>
  <br>
  but not this one
  <code>
  <pre><code>exports.handler = async (event) =&gt; {
      // TODO implement
      event.c_type_\/_customer_type = &quot;Customer Type&quot;;
      const response = {
          statusCode: 200,
          body: event,
      };
      return response;
  };
  </code></pre>
  </code>
  <p>Any clues. Cheers</p>
