Javascript 在运行'；这叫什么

我有3个功能。一个拍照，一个压缩图像，一个上传图像

按下按钮拍照（此功能正常） 另一个按钮被按下上传图片，但首先它运行压缩图像，然后上传它，但我遇到了

ReadableNativeMap无法转换为java.lang.String的错误，这对我帮助很大。我传递的值是否正确

//Take picture
  const takePicture = async () => {
    if (cameraRef.current) {
      const options = { quality: 1, base64: true, skipProcessing: true };
      const result = await cameraRef.current.takePictureAsync(options);
      setImageResult(result.uri);
    }
  };

  //compression image
  const compressimagestuff = async (uncompressedImage) => {
    const manipResult = ImageManipulator.manipulateAsync(
        uncompressedImage,
        { compress: 0.3, format: ImageManipulator.SaveFormat.JPEG }
      );
    return manipResult.url;
  };


  // uploading it to firebase
  const uploadImageAsync = async (uncompressedImage) => {
    let compressedImageUrl = compressimagestuff(uncompressedImage);
    const blob = await new Promise((resolve, reject) => {
        const xhr = new XMLHttpRequest();
        xhr.onload = function () {
          resolve(xhr.response);
        };
        xhr.onerror = function (e) {
          console.log(e);
          reject(new TypeError('Network request failed'));
        };
        xhr.responseType = 'blob';
      xhr.open('GET', compressedImageUrl, true);
      xhr.send(null);
        
    });

    const ref = firebase
      .storage()
      // the file that it will get saved to
      .ref('Front/')
      // giving it a unique name
      .child(await uuid.v4())
    const snapshot = await ref.put(blob);
    blob.close();
    return await snapshot.ref.getDownloadURL();
  };
  

按钮，用于上传拍摄的照片

  const uploadPreviewButton = () => (
    <TouchableOpacity disabled={wasPressed} onPress={() => { uploadImageAsync(imageResult); setWasPressed(true); }} style={[styles.uploadButton, wasPressed ? { backgroundColor: 'red'} : {} ]}>
        <Icon ...>
    </TouchableOpacity>
  );

const uploadPreviewButton=（）=>(
{uploadImageAsync（imageResult）；setWasPressed（true）；}}style={[style.uploadButton，wasPressed？{backgroundColor:'red'}:{}]}>
);
compressimagestuff
是一个异步函数，但您不必等待它。更改此项：

const uploadImageAsync = async (uncompressedImage) => {
    let compressedImageUrl = compressimagestuff(uncompressedImage);

致：

const uploadImageAsync = async (uncompressedImage) => {
    let compressedImageUrl = await compressimagestuff(uncompressedImage);
                          // ^
