To reproduce the bug, just try to drag and drop an element sooner or later on the same day. The error occurance is kinda random but seems to always come from the same issue :
" ERROR TypeError: Cannot read property 'getFullYear' of undefined" on stackblitz and
"Cannot read property 'setHours' of undefined" directly on the page of your documentation.
I tried to track the origin of the issue with no success, but the only thing I can say so far, is that sometimes, the day value (which should be equal to the index of the day column in the view) is equal to the resource column index so => dayIndex * (n resource categories) . I don't know if my explanations are very clear. If you need more details, I can send you my logs. I doubt that this error hasn't been reported sooner, but I didn't found anything.

As I said in my previous message, my packages are up to date (17.4.47) and the issue still occurs.
Here is a sample modified from your demo to fit the configuration I use on my project (2 resources)
As you can see in the below screencapture, the issue is not fully fixed.
