This failure message stands for that Autodesk.Viewing.Extensions.Markups.Core.MarkupsCore was not be initialized properly by rule of thumb, so you can just add a single line markup.load() before console.log(markup); , and it will be gone.

Here is my testing codes, hope you enjoy it~

var viewer;
Autodesk.Viewing.Initializer(options, function onInitialized() {
  var viewerDiv = document.getElementById( 'viewer' );

  viewer = new Autodesk.Viewing.Private.GuiViewer3D( viewerDiv );
  viewer.start( svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError );
});

function onLoadModelSuccess() {
  var config = { markupDisableHotkeys: false };
  markup = new Autodesk.Viewing.Extensions.Markups.Core.MarkupsCore( viewer,config );

  // Missing line here
  markup.load();

  var markupstatus = markup.enterEditMode();
  console.log( 'markupstatus: ' + markupstatus );
}

function onLoadModelError() {
  console.error( 'Failed to load model' );
}
