uploadURL undefined using @uppy/aws-s3

Hi everyone, I am uploading images directly from client side to S3 (@uppy/aws-s3) using pre-signed urls, the images are being uploaded, but “data.uploadURL” in the “upload-success” event is undefined.

        let flyerUploader = new Uppy({
                id: 'flyer',
                debug: true,
                autoProceed: true,
                restrictions: {
                    maxFileSize: 2*1024*1024,
                    maxNumberOfFiles: 1,
                    minNumberOfFiles: 1,
                    allowedFileTypes: ['image/*']
            .use(Dashboard, {
                target: '#flyer',
                inline: true,
                height: 350,
            .use(AwsS3, {
                shouldUseMultipart: (file) => false,
                getUploadParameters (file) {
                    return fetch(Helpers.route('admin/storage/presigned_url'), {
                        method: 'post',
                        headers: {
                            accept: 'application/json',
                            'content-type': 'application/json',
                            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                        body: JSON.stringify({
                            filename: file.name,
                            contentType: file.type
                    }).then((response) => {
                        return response.json()
                    }).then((data) => {
                        return {
                            method: data.method,
                            url: data.url,
                            fields: data.fields,
                            headers: data.headers

        flyerUploader.on('upload-success', (file, data) => {
            console.log(data); //data.uploadURL undefined

Here is an image of data variable

What am i missing here?

After some testing I think is a bug in current version
@uppy/aws-s3: 3.2.1,
@uppy/core: 3.3.1,
@uppy/dashboard: 3.5.0

the same example works fine in older version like
@uppy/aws-s3”: “3.1.1”,

I will post this on github.
