Capture and export a HAR file

When something goes wrong in Octopus we may ask you to provide a HAR file to help us diagnose the problem. This file captures a web browser’s interaction with a site and may provide insight into where and why a specific request is failing.

HAR files may contain sensitive data as they include any pages you visited and associated cookies whilst recording. Depending on what has been recorded, this may allow someone with your HAR file to impersonate accounts or any other personal information submitted during recording.

The following instructions are provided for each browser, starting from the Octopus web portal:

  4. Check the Preserve log box.
  5. Click the Clear button (circle with a slash through it) to remove any existing network recordings in the current session.
  6. Follow the same steps you did initially to reproduce the issue or unexpected behavior.
