I see this error in console:

aura_proddebug.js:61421 WARNING: SecureElement: [object HTMLStyleElement]{ key: {"namespace":"lwcc"} } does not allow setting the type attribute, ignoring!

possibly the method for injecting the style is no longer allowed?

Additionally I would like to use an array for this property but I'm not sure the syntax.

Here's my example code:

global inherited sharing class MyCustomChartDataProvider extends lwcc.ChartDataProvider {
  public override void init(Object initParameter) {}
  
  public override List<lwcc.ChartDataProvider.ChartData> getData() {
    List<lwcc.ChartDataProvider.ChartData> chartDataList = new List<lwcc.ChartDataProvider.ChartData>();
    lwcc.ChartDataProvider.ChartData data = new lwcc.ChartDataProvider.ChartData();
    data.detail = [95.0, 5.0];
    data.labels = ['Label 1','Label 2'];
    data.bgColor = '["rgb(100,100,100)","rgb(200,200,200)"]';
    chartDataList.add(data);
    return chartDataList;
  }
}
