I am writting following code: https://openjavascript.info/2022/12/10/qr-code-scanner-with-html5-qrcode-js/

But getting an error: open QR code parse error, error = D: No MultiFormat Readers were able to detect the code.

Gone through https://github.com/mebjas/html5-qrcode/issues/202 but when I put some changes, it stops giving me this error instead it stops decoding it completely.

I am facing same issue with Demo site, its not scanning anything.

I am doing this on desktop google crome.

I experience a similar one, the qr code could be detected with all other scanners I have tried:

I have the similar problem, the scanner does not work if I use file upload with some specific qrcode. And I found a workaround. For some reason. If I rotate the code slightly (1 degree or something) with canvas. Then it works as expected.

Not sure if it is the same with your case

I'm seeing the same error even though the code is detected and decoded. I removed the console.warn() from the onScanFailure callback for now.
