Cannot read properties of undefined (reading 'row_height')

Gantt
#1

Hello,

I have licensed version of dhtmlx-Gantt 7.1 version.

While loading the gantt chart I am getting below two errors.

  1. Invalid start_date argument for calculateEnd method.
  2. Cannot read properties of undefined (reading ‘row_height’)

If I downgraded version dhtmlx-Gantt 7.0.9 then it is working fine.

Somehow I have fixed the first issue but still getting the second issue 7.1 version

#2

Hello Ghanesham,
Probably, the issue is related to the Gantt configuration, but it is hard to suggest what might be wrong as I don’t see your code.
Please, add your configuration to the following snippet and make sure that the issue is reproduced there:

Then, click on the Share button and send me the link.
Or send me a ready demo with all the necessary Javascript and CSS files so that I can reproduce the issue locally.
