React-Native-Vision-Camera Exception when reading a QR-Code

I'm using react-native-vision-camera to build a QR-Code-Scanner for my app. I followed this guide by dynamsoft: https://www.dynamsoft.com/codepool/react-native-qr-code-scanner-vision-camera.html

In the beginning everything worked fine but now I'm always getting an Exception when reading QR-Codes with my camera. Even with the provided example project in the post it's not working properly anymore.

The detected result I get always has asterisks in it like this: [Attention(exceptionCode:-20111)] *ttp*//**ca*h*st*9*02/*entalobje*ts*book**98420*d*6b**-4***-9e***6*d796*0c*55

I already tried reinstalling the library and everything but I can't get it to work.

Solution

  • vision-camera-dynamsoft-barcode-reader has an internal dependency on DynamsoftBarcodeReader SDK and it needs an active license, which I found out in their other examples. In all their examples, public license are used which has an expiration date.

    Due to this reason, I made a switch to vision-camera-code-scanner. This was already suggested in Community Plugin List of VisionCamera.

    Hope this helps!
