title: URIError: Failed to decode param '/%PUBLIC_URL%/favicon.ico'
body: <p>I am new to webpack and I got the babel loader and css loader to work and project compiles successfully but when I try to access via browser I get the below error. It looks as if PUBLIC_URL is not recognized. I believe I don't know how to configure this.</p>
  
  <p>I appreciate your valuable comments.</p>
  
  <p>Thanks</p>
