I'm attempting to customise a chart.js chart in javascript.
Following the example in charts_api_example_js_override.js, I have a Drupal behavior attaching, can find the chart element by classname, and add the event listener (once).
But my listener is never called:
// a debug point here is hit, and the listener is attached to the canvas element.
el.addEventListener('drupalChartsConfigsInitialization', (ev) => {
// a debug point here is never hit.
}There are no errors in the console.
Is the example and documentation up to date?
Closed: works as designed

In this case the issue is simply module weight. My custom module is sorted alphabetically before "charts", so it just needed a weight decrease in libraries.yml.
Thanks @andileco for taking the time to look at this.
