title: databricks cli: getting b'Bad request error
body: <p>I am trying to use Databricks CLI for the first time. Whenever I try something using cli it gives me the message: &quot;Error: b'Bad Request'&quot; <br>
  This is same for any cli based command<br>
  I am able to do authenticate (Tried with a wrong token and got the authentication error)<br>
  Please find the debug trace for the same below:<br>
  command: databricks fs ls --debug<br></p>
