title: Workfront attask 9.0 - Getting error when trying to POST update
body: <p>I'm trying to post an update to Workfront with no luck. This is my request:</p>
  <pre><code>curl --location --request POST 'https://company.my.workfront.com/attask/api/v9.0/update' \
  --header 'apiKey: {my-api-key}' \
  --header 'Content-Type: application/json' \
  --header 'Cookie: wf-node=http://100.112.130.217:8080' \
  --data-raw '{
      &quot;refObjCode&quot;: &quot;TASK&quot;,
      &quot;refObjID&quot;: &quot;{my-task-id}&quot;,
      &quot;message&quot;: &quot;hello&quot;,
      &quot;threadID&quot;: null,
      &quot;topName&quot;: &quot;&quot;,
      &quot;subObjCode&quot;: null,
      &quot;subObjID&quot;: null,
      &quot;subMessage&quot;: &quot;&quot;,
      &quot;refName&quot;: &quot;&quot;,
      &quot;iconPath&quot;: null,
      &quot;iconName&quot;: null,
      &quot;allowedActions&quot;: [],
      &quot;auditRecordID&quot;: null
  }'
  </code></pre>
  <p>And this is the <code>400</code> response I'm getting, which isn't helpful at all:</p>
  <pre><code>{
      &quot;error&quot;: {
          &quot;message&quot;: null
      }
  }
  </code></pre>
