title: Charles Proxy Map Local
body: <p>I want to "switch off" a legacy tag management tool and replace it with a new tag manager. </p>
  
  <p>Therefore, I want to map a local .js file to set up a tag testing environment. </p>
  
  <p>However, Charles only shows me unknown paths (packages) and therefore I cannot map a local file. </p>
  
  <p>Any clue what setting might cause this issue?</p>
