FileTransfer problems in browser

Ionic Native
1

This code works fine when running on device, but when I run the same code in browser build it fails with FileTransferError code 1. Do anybody have success using FileTransfer in a browser build?

    getPicture(uploadUrl, token) {
        const options: CameraOptions = {
            quality: 100,
            encodingType: this.camera.EncodingType.JPEG,
            mediaType: this.camera.MediaType.PICTURE
        }

        return this.camera.getPicture(options).then(imageData => {
            const fileTransfer: FileTransferObject = this.transfer.create()
            const fileName = 'image.jpeg'
    
            let options = {
                fileKey: 'file',
                fileName: 'image.jpeg',
                headers: {
                    Authorization: 'Bearer ' + token
                }
            }
    
            return fileTransfer
                .upload(imageData, uploadUrl, options)
                
        })
    }
