Difficulties handling asynchronous taks using image-picker and copying files in react-native

const copyPhoto = (source, destination) => {
  if (source === undefined || destination === undefined) {
    return;
  } else {
    RNFS.copyFile(source, destination)
      .then((result) => {
        console.log("

>>>>>>>>>>>>The photo has been copied ");
      })
      .catch((error) => {
        console.log("

>>>>>>>>>>>>Copy photo failed: ", error);
      });
  }
};

const onCameraPress = async () => {
  const options = {
    saveToPhotos: true,
    mediaType: "photo",
    includeBase64: false
  };
  const result = await ImagePicker.launchCamera(options);

  //if the user cancelled the process
  if (result.didCancel) {
    return alert("You cancelled the process");
  }

  const {assets} = result;

  if (assets.length > 0) {
    const decodedUri = decodeURIComponent(assets[0].uri);
    copyPhoto(decodedUri, photoPath);
  }
};
