It's the same as the example

Can you show some sample code?, so I can, easily copy / paste to debug the issue

Same here. Also get cannot convert undefined or null to object

[matthbon]

Removing the empty tooptip, scales, legend and elements from configure seemed to make it work.

So remove this if empty
$this->tooltip([]); // https://www.chartjs.org/docs/latest/configuration/tooltip.html#tooltip $this->scales([]); // https://www.chartjs.org/docs/latest/axes/#axes $this->legend([]); // https://www.chartjs.org/docs/latest/configuration/legend.html#legend $this->elements(); // https://www.chartjs.org/docs/latest/configuration/elements.html#elements
