Debugger Example does not work

[dancingbannana]

Describe the bug
The debugger example gives: Unchecked runtime.lastError: Cannot access a chrome-extension:// URL of different extension.

Im pretty sure await chrome.debugger.sendCommand({ tabId }, 'Fetch.enable', { patterns: [/*...*/]}) Is exactly what causes this.
tabId comes from chrome.devtools.inspectedWindow.tabId

 
To Reproduce
Clone the repo.
Install the debugger example
Go to a website.
Click the extension
Make a network request.
Notice this prints "Unchecked runtime.lastError: Cannot access a chrome-extension:// URL of different extension"

Expected behavior
This should work

Screenshots

Anything additional here. 🌈
This does not happen with Microsoft Edge.

Do you have any other extensions installed that you could try disabling? It's possible they are adding additional content to a page that you are blocked from inspecting.
