When in multi-selection mode and using the delete key for quick deletion, the operation works fine when the selected tasks have no specified task assignments. However, when I assign personnel to certain tasks, the deletion operation throws an error.
I wrote the handling logic referring to the example. I just added the use of the delete shortcut key, and I’m using Vue 3.

Hello,
It is a bug in Gantt, and we are aware of it. The dev team will fix the bug in the future, but I cannot give you any ETA.
There are several workarounds for the bug:
batchUpdate method:silent method and repaint the changes later (though they won’t be sent to the server):Hello,
The dev team fixed the bug with the batchUpdate method:
