🐛App crashed after scanning a qrcode

[sunnystarh]

What's happening?

I have a crash after scanning the QR code. I haven't found the reason yet. I have released the relevant code and logs. I hope someone can answer it.

Reproduceable Code

const onAuth = async () => {
    const grantedStatus = await Camera.requestCameraPermission();
    if (grantedStatus === 'granted') {
      setHasCameraPermit(true);
    } else {
      setHasCameraPermit(false);
    }
  };
  useEffect(() => {
    onAuth();
  }, []);

  const codeScanner = useCodeScanner({
    codeTypes: ['qr'],
    onCodeScanned: codeData => {
      if (codeData[0].value) {
        verificationCodeData.current = codeData[0].value;
        if (source === 'fromScanIcon') {
          scanCodeFromScanIcon();
        } else if (source === 'fromBindButton') {
          scanCodeFromBindButton();
        }
      }
    },
  });
       
      {device != null && HasCameraPermit (
        <Camera
          photo={false}
          video={false}
          isActive={isFocused}
          device={device}
          codeScanner={codeScanner}
          style={StyleSheet.absoluteFill}
          torch={TorchMode}
        />
      )}

VisionCamera Version

v3.6.4

Can you reproduce this issue in the VisionCamera Example app?

Yes, I can reproduce the same issue in the Example app here

Additional information

• I am using Expo
• I have enabled Frame Processors (react-native-worklets-core)
• I have read the Troubleshooting Guide
• I agree to follow this project's Code of Conduct
• I searched for similar issues in this repository and found none.

In my case, the app only crashes after the first QR scan. Once I restart the app, it proceeds to scan QR codes without any crash. I just came across this issue yesterday. I'll definitely share any findings under this thread.

  I have the same issue please tell what we can do

[hovo96]

@mrousavy please take a look at this

[mrousavy]

@mrousavy please take a look at this

@apadev666 why?

[hovo96]

@manuelbieh any ideas why its happening?
as I understand there are many users with this same problem, I tried to downgrade version of package but nothing helped. Can you help ?

[yasirlateef]

@apadev666 this could happen for a number of reasons. Firstly, it could happen if you don't configure your camera properly. Try removing all the props except for the required ones and try adding them one-by-one to see what breaks.

[yasirlateef]

There is no apparent bug related to the scanner functionality per-se.

[hovo96]

I don't have any prop just standard initialization used from docs

[hovo96]

<Camera
      photo
      device={device}
      isActive={isActive}
      codeScanner={codeScanner}
      style={[styles.absoluteFill]}
      torch={isTorchEnabled ? 'on' : 'off'}
    />
    
    here is code

[hovo96]

it can crash for the first time but also after for example 10 attempts

I looked up issue 2090 and someone answered that changing react-native-vison-camera to version 3.5.1 works fine. So I tried lowering the version. Fortunately, I scanned the qrcode from afternoon to now, the app will not crash when scanning the qrcode.（(I tried upgrading to v3.6.6 and v3.6.8 yesterday, and also tried downgrading to v3.6.0, but there was always a crash）

@sunnystarh it's possible to update your log with more details before Fatal signal ?, there's some vision-camera logs that can help understand what's happening
