Failed to transcode QR codes pointing to localhost URLs #33

Open plmr-org opened 2 months ago

Currently writing an application that generates QR codes as BLOBs in the back-end and sends them to the front-end where they are displayed. Here's the QR code in question: image

It should be pointing towards http://localhost:3000/<base64> or something of that nature. The QR code works through my Android phone's built-in QR code scanner, though not through the extension.

Strangely there are also no error messages raised by the extension. Here's what I received which may be more useful: 2024-07-30_14-24

This also happens on Firefox by the way: 2024-07-30_14-25 Sorry for the comment spam.

Hi, thanks for the bug report. However I can't seem to reproduce this on my side. Can you provide the HTML source for the web page where this issue happened?

plmr-org commented 1 month ago

It effectively boils down to this:

<div className="h-80 w-80">
    <img
        alt="QR Code"
        height={450}
        src={qrCode}
        width={450}
    />
</div>

I'm now wondering if the image being encapsulated in a div is what could be causing this issue.

If this doesn't suffice, I plan to publicise the page anyway for diagnostic purposes if that's any easier for you.

Weirdly, region scanning works fine, the option to scan the QR code in the image is what's problematic as shown here: image

Yes, I suspect that this is a image loading issue. It would be nice if you could provide the relevant parts of the rendered HTML code (not your framework code). I'm specifically interested in these info:
