Hello Roufa,
Thank you for sending me the project.
I don’t specialize in Angular and ASP.NET, so I won’t be able to tell you what is wrong in Angular configuration or on the backend side.
But I see that when you initialize the data processor, you probably do not attach it to Gantt. So when I add a task (even without the backend), Gantt doesn’t try to send the data to the server side:

But after I add the data processor correctly, Gantt tries to send the data to the server side:

/*const dp = gantt.createDataProcessor({
	task: {
		update: (data: Task) => this.taskService.update(data),
		create: (data: Task) => this.taskService.insert(data),
		delete: (id) => this.taskService.remove(id)
	},
	link: {
		update: (data: Link) => this.linkService.update(data),
		create: (data: Link) => this.linkService.insert(data),
		delete: (id) => this.linkService.remove(id)
	}
});*/
var dp = new gantt.dataProcessor("/api");
dp.init(gantt);
dp.setTransactionMode("REST");
