How to upload to S3 bucket?

Hi, Is there a way to upload to S3 bucket?

I tried it like this and got the following error:

const options = {
    url: 'https://s3.amazonaws.com/mybucketname',
    method: 'POST',
    path: uri, // /Users/user/Library/.../5D94544E-E33B-475E-BB3F-5BFA72E15A63.jpg
    type: 'multipart',
    headers: {
    },
    field: 'uploaded_media',
    region: "us-east-1",
    accessKey: 'myaccesskey',
    secretKey: "mysecretkey",
    // Below are options only supported on Android
    notification: {
      enabled: 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!`)
    });
    Upload.addListener('completed', uploadId, (data) => {
      console.log('Completed!', data)
    })
  }).catch((err) => {
    console.log('Upload error!', err)
  });

and i got this error:

       import Upload from 'react-native-background-upload';
       import { S3Policy } from 'common/react-native-aws3/S3Policy'; // https://github.com/benjreinhart/react-native-aws3

        const fileInfo = await Upload.getFileInfo(videoPath);
        const options = {
          type: 'multipart',

          headers: {

If like me you are looking to simply upload to a public bucket, here is the code I used that worked:

const options = {
            url: 'https://s3-eu-west-1.amazonaws.com/xxxxxxxx/',
            path: result.fileCopyUri,
            method: 'POST',
            type: 'multipart',
            field: 'file',
            maxRetries: 2, // set retry count (Android only). Default 2
            headers: {
              'content-type': 'application/octet-stream', // Customize content-type
            },
            parameters:{
              key: result.name
            }
          };

          Upload.startUpload(options)
