posting with formdata not working

tried doing something like

var fileData = new FormData();
      fileData.append("File1", file);

return axios({
                    method: 'post',
                    url: response.data.ChunkUri,
                    data: fileData,

                });

this returned an error from the server saying that there was no file sent. But…

vs jquery which worked and the file uploaded successfully.

                var options = {
                    type: "POST",
                    url: response.data.ChunkUri,
                    data: fileData,
                    cache: false,
                    contentType: false,
                    processData: false,
                    success: function(e){
                            console.log("YAY:: " + e);
                    },
                    error: function(a){
                        console.log("failed:: ");
                    }

                };
                return $.ajax(options);

As @kalaspuffar pointed out, filename can be passed as the third parameter to FormData#append:

fileData.append("File1", file, "file.js");

@nickuraltsev’s answer in https://github.com/mzabriskie/axios/issues/318#issuecomment-218948420 really helped me out.
