How to generate a HAR file?

HTTP Archive (HAR) stores all web requests made by the browser, including:
  1. The request and response headers and bodies.
  2. Connection, response, and download times.
  3. Failed requests or network errors.

  2. Refresh the page and once again perform the action to record the issue as output.
