  <pre><code>' Could not render this component, see the console' 
  </code></pre>
  
  <p>(shown in first image) was an error message or if it can just be ignored (or maybe a warning that encompass a lot and therefore is not always applicable?). I am testing uploading a file (as shown in first image). The code that is getting hit (the nodejs javascript which corresponds to this post) is shown in the code sample below figure 1. it is very simply but once line 23 gets executed the 'could not render' message appears. However, the response of 'Hello World!' does get displayed in swagger. I looked around online for the meaning of this message but the only postings about this didn't seem to be asking about this message but an error message in the 'server response' section of swagger. </p>
