Can you please assemble a minimal demo of your code (for example on jsfiddle) so I can reproduce your issue. Otherwise I can't help you.

You could modify this demo until your issue appears.

I am very sorry, jsfiddle I use less; I installed vue-qrcode-reader : 2.0.4 ; I have a problem setting the "camera" parameter in the <qrcode-stream tag; <qrcode-stream @decode="onDecode" @init="onInit" :camera="camera" /> Scanning is only performed when the “camera” parameter is “auto”; When the “camera” parameter is “rear” or “front”, an error is displayed. If you can, I hope you can give me some ideas.
