Plot not uploading to plotly

I found plotly about a week ago and have been using it in a little node.js project, and it has been working perfectly fine, but yesterday, when I use plotly.plot to upload a graph, the usual message in console does not display and instead just says “undefined”. I tried changing my API key, and that hasn’t helped. I even used the sample code:

var plotly = require("plotly")("energy_sync", "key");

var trace1 = {
    x: [1, 2, 3, 4],
    y: [10, 15, 13, 17],
    type: "scatter"
  var trace2 = {
      x: [1, 2, 3, 4],
      y: [16, 5, 11, 9],
      type: "scatter"
  var data = [trace1, trace2];
  var graphOptions = {filename: "basic-line", fileopt: "overwrite"};
  plotly.plot(data, graphOptions, function (err, msg) {

the output is still “undefined”

Thanks for writing in.

What was the msg message saying previously?

Something like “High five! Your graph has been uploaded using the name of (insert name)”
