How do I create a HAR file for troubleshooting AM?

Overview

A HAR file is output by browser developer tools and other browser extensions. It is essentially a recording of interactions between the browser and application in JSON format; it can be very useful for troubleshooting as it can help identify where the issue is occurring.

2. Select the Preserve log option to ensure the entire request is saved, even if you are redirected.
3. Enter the URL where you have been experiencing issues and re-create the issue. Do not open a new browser tab as Chrome records details on the tab initially shown when the Developer Tools were launched.
