Create a HAR file with cookies
Sometimes, the simple HAR file is not enough to troubleshoot your issue. In those cases we might ask you to share a file that includes cookie data. To generate this file, follow these steps:
Open Google Chrome.
Press Ctrl+Shift+I (Windows/Linux) or Cmd+Option+I (Mac) to open Chrome Developer Tools.
Go to the Network Tab and select the settings icon:
In the newly opened overlay, search for the “Allow to generate HAR with sensitive data” option and check it.
Close the overlay and go back to the Network tab.
Make sure that the Preserve log option is enabled in the Network tab.
To start recording, click the round, gray recording button in the Network tab. If this button is gray, no recording is taking place. If the button is red, a recording is currently being created.

Reload the page where the problem occurred, then reproduce the problem.
To save the recorded data, click the download icon in the top right corner and make sure to select the “Export HAR (with sensitive data)” option:
