Vue QRCode Reader

Hi all, I install vue-qrcode-reader for the QR code reader function. But while the app runs, the web console got an error as below:
Unhandled Promise Rejection: TypeError: undefined is not an object (evaluating '_vm._self._c'

It looks like we cannot use the native Vue QRcode reader library in Ionic directly.
May I know which library you used to implement QRcode reader in Ionic Vue?

Thank you
