I keep getting this error and I don't know why, I tried comparing it with the example to see where the possible error could be but could not find a solution. Can someone assist me please.

utils.js:217 TypeError: Cannot read property 'column_paths' of undefined
    at HTMLElement.draw (scroll_panel.js:377)
    at HTMLElement.r.value (utils.js:215)
