JS Errors not reporting

Hello, I just recently discovered that not all errors are being reported to NR Browser. If I look in the browser > JS Errors tab for the last 60 minutes there is nothing on my /checkout/ PageURL but I just witnessed an error about 20 minutes ago.

Any idea why this would be?

Hi, @dustin6: How are you deploying the Browser agent? This can happen when the agent is not the first JavaScript to execute on the page. If you are copying and pasting the Browser agent, it should be an inline script tag (not referencing an external .js file) as close to the top of the head section as possible.
