title: IBM Language Translator returns 403 Forbidden upon identify()
body: <p>I followed the official documentation to create a multilingual Watson assistant outlined here:
  <a href="https://github.com/with-watson/multilingual-chatbot" rel="nofollow noreferrer">https://github.com/with-watson/multilingual-chatbot</a></p>
  
  <p>However, after deploying the function on IBM Cloud and testing the deployed function via IBM Cloud CLI with the below command, I am getting an error (logs below):</p>
  
  <blockquote>
    <p>bx wsk action invoke translator --result --param text "Hallo, ich habe eine Frage."</p>
  </blockquote>
  
  <p>{
      "error": "The action did not return a dictionary."
  }</p>

  <p>Looks like the API key is recognized but not permitted to be used for this action, however the key being used does return the right values when used via cURL. </p>
  
  <p>The code executed in main is the same as provided on the Github above, I did not make any changes. </p>
  
  <p>Any ideas on how to fix this issue? Thanks!</p>
