🐛 takeSnapshot returns path without separated file extension without .jpg

What's happening?

When using the takeSnapshot method from the Camera module of the Vision Camera library, the returned path does not include a separated file extension, and the file extension is not .jpg. This results in an invalid file path that cannot be used to render the image, causing a crash error.

Reproduceable Code

const onStartRecording = async () => {
  // Check if RNFS.PicturesDirectoryPath is defined
  console.log('RNFS.PicturesDirectoryPath:', RNFS.PicturesDirectoryPath);

  var path = RNFS.PicturesDirectoryPath
    ? `${RNFS.PicturesDirectoryPath}/MediaEditor`
    : `${RNFS.DocumentDirectoryPath}/MediaEditor`;

  if (!path) {
    console.error('Invalid file path');
    return;
  }

  const exists = await RNFS.exists(path);
  if (!exists) {
    await RNFS.mkdir(path);
  }
  if (mode === 'photo') {
    try {
      if (!cameraRef.current) {
        console.log('Camera reference is null');
        return;
      }

      const photo = await cameraRef.current.takeSnapshot({
        flash,
        enableShutterSound: true,
        enableAutoRedEyeReduction: true,
        quality: 100,
      });

      if (photo?.path) {
        let filePath = `file://${photo.path}`;
        console.log('Captured Image Path:', filePath);
        const imageID = `${Date.now()}-${Math.random()}`;
        const newImage = {
          id: imageID,
          fileName: filePath.split('/').pop(),
          height: photo.height,
          width: photo.width,
          type: 'image',
          uri: filePath,
          additionalImages: [],
          texts: [],
          stickers: [],
          matrix: [],
        };

        setImages([newImage]);
        setActiveStoryIdx(imageID);
        setOverlapExtra([newImage]);
        setFilter(false);
      }
    } catch (error) {
      console.error('Error capturing photo:', error);
    }
  }
};

Possible Solutions

Check the VisionCamera version: Make sure you are using the latest version of VisionCamera. You can check the version by running npm ls react-native-vision-camera or yarn ls react-native-vision-camera.
Check the camera device: Make sure the camera device is properly configured. You can check the camera device by running console.log(cameraRef.current.getDevice()).
Check the file path: Make sure the file path is properly formatted. You can check the file path by running console.log(photo.path).

Conclusion

The takeSnapshot method from the Camera module of the Vision Camera library returns a path without a separated file extension and without the .jpg file extension. This results in an invalid file path that cannot be used to render the image, causing a crash error. To fix this issue, you can try checking the VisionCamera version, the camera device, and the file path.

Future Work

Improve the takeSnapshot method: Improve the takeSnapshot method to return a properly formatted file path with a separated file extension and the .jpg file extension.
Add error handling: Add error handling to the takeSnapshot method to handle cases where the file path is invalid.
Improve the camera device configuration: Improve the camera device configuration to ensure that the camera device is properly configured.
