title: Is __dirname unusable this way or is it undefined?
body: <p>I have set a variable that is shown below
  <br><code>pathImage = __dirname + '/bot.jpg;</code>
  <br><br>
  I want to pass the value of <code>pathImage</code> to IconUrl from my .env file. This is how I do it. <br><code>var invite = new Welcome(process.env.IconUrl=pathImage, process.env.BotVersion);</code></p>
  
  <p>Finally, I'm getting this error from NodeJs</p>
  
  <blockquote>
    <p>[onTurnError]: SyntaxError: Unexpected token U in JSON at position 633</p>
  </blockquote>
  
  <p>But, this works for me (setting path manually, not preferable way)<br>
  <code>var invite = new Welcome(process.env.IconUrl='C:/Users/Mackhem/Desktop/testBot/bot.jpg', process.env.BotVersion)</code></p>
