Series points error

[KamilKubik]

Expected behaviour

After adding a new series with visible: false property, setting a color.patternIndex property on another series, and viewing it in the full screen, I should be able to exit the full screen by clicking it in the menu.

Actual behaviour

After adding a new series with visible: false property, setting a color.patternIndex property on another series, viewing it in the full screen and trying to exit the full screen by clicking it in the menu, the TypeError: undefined is not an object (evaluating 'a.points.forEach') error occures.

Hello @KamilKubik, thanks for reporting this issue!
Simplified demo: https://jsfiddle.net/BlackLabel/r5kbh7ef/1/

Unfortunately, it is impossible to workaround, since this part of code is added via addEvent.
Possible fix would involve checking series' visibility here:

highcharts/ts/Extensions/PatternFill.ts

Lines 637 to 651 in 5015369

	this.series.forEach(function (series: Series): void {
	series.points.forEach(function (point: Point): void {
	const colorOptions = point.options && point.options.color;
	if (
	colorOptions &&
	(colorOptions as PatternFill.PatternObject).pattern
	) {
	(colorOptions as PatternFill.PatternObject).pattern
	._width = 'defer';
	(colorOptions as PatternFill.PatternObject).pattern
	._height = 'defer';
	}
	});
	});
