TypeError: Cannot read property 'ToString' of undefined when bar chart is rendering with data.

Codepen: https://codepen.io/jfalter/pen/rNedKOw

Whenever I attempt to render a bar chart with data, I get the following error message:

Uncaught (in promise) TypeError: Cannot read property 'toString' of undefined at Function.value (apexcharts:6 at t.value (apexcharts:6) at t.value (apexcharts:6) at t.value (apexcharts:14) at t.create (apexcharts:6) at apexcharts:14 at new Promise (<anonymous>) at t.value (apexcharts:14) at apexcharts:6 at Array.forEach (<anonymous>)

When I look at the Apexcharts Javascript file, I see this throwing an error:

key: “escapeString”, value: function(t) { var e = arguments.length > 1 && void 0 !== arguments[1] ? arguments[1] : “x” , i = t.toString().slice(); //This is what’s throwing the error. return i = i.replace(/[` ~!@#$%^&*()_|+-=?;:'",.<>{}[]\/]/gi, e) }

Note that it works fine if I render with empty data and category arrays.

I have the same error! I thought that I was the only one.

Thanks for reporting. It’s a major bug and I had to immediately release a patch version as this might have broken many existing charts.

Please upgrade to v3.20.2
