  <p>This is what I am getting and I cannot proceed from this</p>
  
  <pre><code>    TypeError: 'encoding' is an invalid keyword argument for this

  <p>I would at least like to know what is the problem</p>
  
  <p>It's still okay if it's not solvable</p>
  
  <p>I would love to get suggestions with chatbot too</p>
  
  <p>Thanks.</p>
