QR code scanning issues via browsers on windows

Apologies for the confusion. This issue was not via the extension, there was a button on the one time passcode field on my.1password.com while I was editing an entry. Hovering over it said it would work with things copied to the clipboard (which is what I was trying to do) or on screen (which is why I invoked ms paint as a alternative attempt), and clicking on it gave the exception message that I posted above in the dev console.

Your documentation even says that it should work via clipboard or on screen:

Interestingly today the button no longer exists while editing the one time password field on my.1password.com and it is now just a regular text box:

So perhaps someone on the development team noticed this was broken and took it down already while it's fixed?
