Zoom in and out with highcharts v9.1.2

[NouranHalawa]

I have a problem with highcharts when zoom in and out with the following log trace:

----------Exception 1-------
java.lang.JsException: TypeError: Cannot convert undefined or null to object

Any clue why this happens?

Hi,

Welcome to our forum & thanks for the question!

It seems to me like it might be related to some of your custom logic or something with your config.

This error does not appear in a simple Highcharts scenario: https://jsfiddle.net/BlackLabel/x1drh2ya/

Could you please try to reproduce this issue and send me a link? (You could use JSFiddle that I've sent as a starting point).

Only then will I be able to help.

Best regards!
