the only suggestion i can give you base on your current code is to use `?.` operator if it did'nt work please show more parts of your code const ctx = document.getElementById("axes_line_chart")?.getContext("2d");

Wrap it into a function like this. window.onload = function() { const ctx = document.getElememtById(“your canvas id”).getContext(“2d”); };
