Why Am I Getting This Error Chrome-extension://invalid

In my case when I played audio sound/beep.ogg, it worked but console contained same error. I solved it by adding it to web_accessible_resources in manifest.json:

I discovered what happened. The corporate network is protected by their proxy.

We monitored the calls and discovered that: The cast lib tries to call the cast extension "pkedcjkdefgpdelpbcmbmeomcjbeemfm", which is not installed at %appdata% folder.

The Chrome tries to download it at: gvt1.com and the network blocked this domain. After talking to the network administrator, we released the domain and it worked.

Solution 3:

Sometimes this happens because of a failed extension. If you go to the Network Tab in Chrome Developer tools, and hover over the Initiator column on the line showing invalid in red, you'll see something like

chrome-extension://jjfblogammkiefalfpafidabbnamoknm ...

Then go to the Extensions page for Chrome, and you'll see an extension with that ID. Disable or Remove that extension.
