Attached is an example with the error, tried to set syncDataOnLoad: false, but the issue persists.

"Hi,
I’m experiencing an issue while updating Gantt task data (when the tasks are segmented).

The data changes dynamically (via filtering), but after the second update, I encounter the following error:

Transaction.js:83 Uncaught (in promise) Error: Unknown identifier ModelClass-fb37e228-8396-4a41-acd2-b3284a932ff7.$.manuallyScheduled
at throwUnknownIdentifier (Transaction.js:83:9)
at EngineTransaction.onReadIdentifier (Graph.js:133:9)

I’ve created a simple project example to help you reproduce the issue:

• Click on “Change the data for the first time” – the data updates correctly.
• Click on “Change the data for the second time” – an error is thrown.

Please let me know if my project is missing any configuration or if there’s a way to fix this issue."
