[Bug?]Cannot create and edit Real Curve in 3.8 Editor

Cocos Creator
#1

In the video, i recorded how the bug happened. I created a real curve in A.ts script with the code copied from cocos page:
https://docs.cocos.com/creator/manual/en/scripting/decorator.html

import { _decorator, Component, Node, RealCurve } from 'cc';

const { ccclass, property } = _decorator;

@ccclass('A')

export class A extends Component {

    @property(RealCurve)

  realCurve:RealCurve = new RealCurve();

    start()

    {

       

    }

}

Upon clicking to other object, then back to the object containing Real Curve, the error in the editor show. Here is the log

error: [Window] Cannot read property 'map' of undefinedTypeError: Cannot read property 'map' of undefined

Thank you for the feedback, we will look into this issue.

Hello, we will support new RealCurve in the future so you can edit it in the editor. For the time being, you can give the property default data, as shown in the following code

    @property(RealCurve)
    realCurve = (() => {
        const curve = new RealCurve();
        curve.assignSorted([
                [0,{value: 0}],
                [1,{value: 1}],
        ]);
        return curve;
    })();
