I tried to upload a file with react-native-background-upload, but my order of parameters is not as required. How can I fix it? Seem I can't change the order of my request.

Here is my code

  const fileInfo = await Upload.getFileInfo(path);
  const options: any = {
    url: url,
    path: path,
    method: 'POST',
    type: 'multipart',
    field: 'file',
    maxRetries: 2, // set retry count (Android only). Default 2
    headers: {
      'content-type': fileInfo.mimeType, // server requires a content-type header
      'content-length': `${fileInfo.size}`,
    },
    parameters: {
      key: `${fields.key}/${fileInfo.name}`,
      acl: fields['acl'],
      bucket: fields['bucket'],
      'X-Amz-Algorithm': fields['X-Amz-Algorithm'],
      'X-Amz-Credential': fields['X-Amz-Credential'],
      'X-Amz-Date': fields['X-Amz-Date'],
      'X-Amz-Signature': fields['X-Amz-Signature'],
      Policy: fields['Policy'],
      'Content-Type': fileInfo.mimeType,
    },
    notification: {
      enabled: true,
    },
    useUtf8Charset: true,
  };

  Upload.startUpload(options)
    .then(uploadId => {
      console.log('Upload started');
      Upload.addListener('progress', uploadId, data => {
        console.log(`Progress: ${data.progress}%`);
      });
      Upload.addListener('error', uploadId, data => {
        console.log(`Error: ${data.error}%`);
      });
      Upload.addListener('cancelled', uploadId, data => {
        console.log('Cancelled!', data);
      });
      Upload.addListener('completed', uploadId, data => {
        // data includes responseCode: number and responseBody: Object
        console.log('Completed!', data);
      });
    })
    .catch(err => {
      console.log('Upload error!', err);
    });

This is the error message from s3

It requires key as the first parameter
