React JS - 未捕获的 NotFoundError：无法在“Node”上执行“insertBefore”：

Question

新手上路，请多包涵

我有一个 div 其中另外三个 div 如下附加。通过循环来自 componentWillReceiveProps() 的 api 结果来设置状态值。但是我遇到了一个错误的问题

Uncaught NotFoundError: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node

如果 api 结果为空，则获取

Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

我怎样才能解决这个问题？

 componentWillReceiveProps(nextProps) {
    var sub1 = [], sub2 = [], sub3 = [];
    if(result) {
        result.sub1.map((item, index) => {
            sub1.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })
        result.sub2.map((item, index) => {
            sub2.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })
        result.sub3.map((item, index) => {
            sub3.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })

        this.setState({ subDiv1:sub1, subDiv2:sub2, subDiv3:sub3 })
    }
}

render() {
    return(
        <div className="row top_bar">
            <div className="search left col-xs-5 col-sm-4 col-md-5 col-lg-6">
                <form>
                    <input type="text" id="search_box" name="search_box" placeholder="Search" onKeyUp={this.keyUpFn} />
                </form>
                <div className="div1">
                    { this.state.subDiv1 }
                    { this.state.subDiv2 }
                    { this.state.subDiv3 }
                </div>
            </div>
            <div className="top_right col-xs-7 col-sm-8 col-md-7 col-lg-6">
                <div className="top_outer">
                </div>
            </div>
        </div>
    )
}
