The error you are seeing tells us that Adobe Analytics is not found. Which means you need to ensure the Chrome (Im assuming) Extension you are using needs to be running on a page that has Adobe Analytics.
So what you will need to do is make sure you are on a page that has Adobe Analytics firing.
Try these steps:
1. Enable the extension in Chrome to be in incognito
2. Go on to a new incognito window
3. Go to a page that has Adobe Analytics
4. Open the extension
5. Check if you see it firing or do a page refresh
