Error when using resources with custom scales

Gantt
#1

I’m using gantt with custom scales and custom resources, workload calculation made by us.
When I try to load data an error occurs:

this.gantt.clearAll();
this.resourcesStore.clearAll();
this.resourcesStore.parse(this.resourceData);
this.gantt.parse(ganttData);
this.gantt.refreshData();

Today I notice that same error occurs when scale level is set:

this.gantt.ext.zoom.setLevel(level);

Error:

I was able to investigate problem a bit more and problem is in this line:

image987×144 10.4 KB

Fore some reason I have 3 horizontalViews and 2 verticalViews.
Horizontal views:

image1054×1177 81 KB

Vertical views:

image1174×816 56.3 KB

And my layout configuration:
layout.json (1.9 KB)

Hello Wolland,
Thank you for sending the layout configuration and providing the additional details.
It seems that you encountered a bug that was fixed in the 7.1.9 version:
