类型错误: 无法读取未定义的属性“存在”

• 我正在尝试为 JSX 文件编写测试用例
• 在这一点上，我能够通过道具类型...
• 但不是我通过道具的地方...
• 我在运行测试用例时遇到错误。
• 在下面提供我的错误、测试用例和代码...
• 类型错误：无法读取未定义的属性"存在"
• 不知道如何使其与此共存。
• 它在这个函数调度侧边栏存在。
• 你能告诉我我需要如何把它放在我的测试用例中吗

JavaScript错误

测试用例

`javascript`
import {expect} from 'chai';
import React from 'react';
import TestUtils from 'react-addons-test-utils';
import initializeJsDom from './test-utils/dom.js';
import {SportsPageClasses} from 'sports-css-grids';
import sportsMockUpStandard from '../src/sports-template-standard';
describe('shallow renderer tests for sports-template-standard ', function() {
    let shallowRenderer = TestUtils.createRenderer();
    console.log("shallowRenderer" + JSON.stringify(shallowRenderer));
    it('should render correctly', () => {
        //var rightPanel ="some string";
        var layout ="some string";        
        var hasSidebar = function(){
            done();
        }
        console.log("here1");
        //this.props.layout.rightPanel.exists = 'some value';
        shallowRenderer.render(<sportsMockUpStandard
            headerClass='8887' 
            layout= {{id: 100, text: 'hello world'}} 
            sidebar= {[{hasSidebar},{id: 100, text: 'hello world'}]} 
            title={"Demo"} />);
        // shallowRenderer.render(<sportsMockUpStandard
        //layout= {{id: 100, text: 'hello world'}}  />); 
        console.log("here2");
    });
});

片段代码

`javascript`    
dispatchSidebarExists(props) {
    let hasSidebar = !!props.sidebar;
    // infinite loop without this check
    if (hasSidebar !== this.props.layout.rightPanel.exists) {
        this.props.dispatch(setSportsCornerState({
            exists: hasSidebar
        }));
    }
}

整个代码

export function setSportsCornerState(stateString) { return { type: 'SET_HEADERPANEL', stateString }; } ```
