Uncaught TypeError: Cannot read properties of undefined (reading 'forEach') about highcharts

[hubertkozik]

The change will be included in the next release of Highcharts. We do not have any specific ETA for the next release at this moment, as Highcharts v11.4.0 was released yesterday. Until that, you can copy-paste the IIFE function from this demo: https://jsfiddle.net/BlackLabel/wsfo7e1u/ as a plugin to your project.

Hi @shashikiran797!
I was trying to reproduce your issue, but everything is working correctly - please check the demo below.
Demo: https://jsfiddle.net/BlackLabel/vkg542yq/

Can you reproduce the issue in the online editor?

[shashikiran797]

Yes @hubertkozik .
Even I am not able to reproduce this always.
It happens intermittently.

Can you please let me know how axisTypes is derived for a series? or point me to the code / documentation
I see the issue only when the axisTypes for the series has colorAxis in it.

[hubertkozik]

axisTypes is an internal property for series, which is used to set, which axes types can be used for this kind of series. There is no documentation for this option, it is used internally.

colorAxis is populated in many places, but it is added to axisTypes here:

highcharts/ts/Core/Axis/Color/ColorAxisComposition.ts

Line 308 in 88128da

function onSeriesBindAxes(

As I said before, it is also an internal method, not official one to use by the users.

bindAxes is called internally during the series initialization. This method is also only for internal use, not official.

What inputs do I need to pass to make sure axisTypes does not contain colorAxis?
In my case, the issue happens only when the axisTypes for the series has colorAxis in it.

@hubertkozik
I have raised a pull request with the fix for the problem I am facing.

@shashikiran797 We are not able to understand the issue fully without reproducing the problem in the online editor, e.g. JSFiddle. As I asked you before, can you reproduce the issue in the online editor? You can use this demo for a start: https://jsfiddle.net/BlackLabel/vkg542yq/

@hubertkozik I think we can apply @shashikiran797 's changes safely. I added some type safety and will post a PR with the improved typing including the suggested fix.

When can I expect this change to be available for use from npm?
Will this change be applied on any patch version?
