Sometimes in the course of deeper troubleshooting, a CompTIA Representative will ask that you create an HTTP Archive file (HAR) of your LTI launch. This file records a period of traffic through your internet browser and can provide valuable technical insight into exactly what your LMS is sending to our system, including authentication info, integration parameters, and more.
For errors that occur as your LMS opens a new tab
By default, a browser's Developer tools only records the tab where it's opened. If you need to troubleshoot an issue that occurs as part of a new tab opening, you'll need to turn on a setting that allows your browser's Developer Tools to follow and record the traffic in the new tab.
- Open your browser's Developer Tools by clicking the three-line or three-dot menu in the upper right, and selecting More Tools > Developer Tools.
- Chrome/Safari: Click the Gear icon to the left of the X (not the very similar icon under the X).
- Edge: Click the three-dot menu in the upper right of Dev Tools and select Settings.
- Firefox: At time of writing, creating a HAR of a new-tab event is not possible.
- Scroll to the bottom of the screen that appears, and under the Global section, check the box for Auto-open DevTools for popups.
- Follow the instructions in the section below to generate the HAR file.
Generating a HAR File
- Navigate to the point just before the issue in question occurs.
- Visit this Zendesk article and follow the instructions through the step of exporting/saving the HAR file, and then you may stop.
- Please note that your Dev Tools must already be open as you reproduce the issue, otherwise, your HAR file won't contain any useful information.
- Send the file to the CompTIA representative who requested it.
