We may need a HAR file to help further troubleshoot some LTI issues. A HAR file helps capture a web browser's interaction with a site. Specifically, we usually need the HAR file relating to the LTI link launch, which our LTI engineers can use to investigate.

Steps to get a HAR file

1. Check if your link is set to open in a new tab/window.

If YES, follow the instructions in our Additional steps.

If NO, proceed to Step 2.

2. Right-click on the page and click Inspect.

3. Open the Network tab with the link ready to launch. 

4. Launch the LTI link by clicking on it.

5. Filter network results by "lti".

6. On the one with "provider", right-click and hit Save All As HAR With Content.

If you do NOT see anything listed for "provider", please locate the request called "oidc" and save that instead.

Additional steps if the link is set to open in a new tab
