How do I Capture a HAR File?

HAR files capture information to help Amplify troubleshoot issues you may be having.

Updated over a week ago

If you are experiencing complex technical issues, the Amplify support team may ask to collect additional information via HAR files. HAR files can be saved from Chrome or Safari to provide details about how your browser interacts with the Amplify platform at the moment an error occurs.

Chrome Instructions

When the issue you’d like to report occurs:

  1. In Chrome, tap or click the three-dot Settings menu. Click More tools > Developer Tools. A new panel opens at the right of your Chrome window.

  2. Click the Network tab. You may need to click >> to view it.

  3. Ensure the circle in the top left of the DevTools window is red rather than dark grey. Select the box labeled Preserve log, and clear the box labeled Disable cache.

  4. Once you recreate the issue, right-click any row in the table and select Save as HAR with content. Save the HAR file to your computer, noting the directory.

  5. Attach the HAR file to an email and send it to your Amplify contact.

Safari Instructions

When the issue you’d like to report occurs:

  1. In the Safari menu, click Develop >Show Web Inspector. A panel opens in your Safari window.

    If Develop is not an option in your Safari menu, click Safari > Settings. Click the Advanced tab, and select the box labeled Show features for web developers.

  2. Click the Network tab in the web inspector panel.

  3. Click the menu button to the right of "All" and select Preserve log.

  4. Re-create the issue, and click Export on the far right of the network tab. Save the HAR file to your computer, noting the directory. You may need to make the web inspector panel wider to see the Export button.

  5. Attach the HAR file to an email and send it to your Amplify contact.
