示例代码：

<template>  
    <view class="content">  
        <image class="logo" src="/static/logo.png"></image>  
        <view class="text-area">  
            <text class="title">{{title}}</text>  
        </view>  
    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
                title: 'Hello',  
                obj: {}  
            }  
        },  
        onLoad() {  
            this.testFun()  
        },  
        methods: {  
            testFun() {  
                this.obj = {  
                    'test.name.txt': 'frank',  
                    'test.age.num': '20'  
                }  
                setTimeout(() => {  
                    this.title = '测试'  
                    console.log(this.obj)  
                }, 100)  

            }  
        }  
    }  
</script>  

<style>  
    .content {  
        display: flex;  
        flex-direction: column;  
        align-items: center;  
        justify-content: center;  
    }  

    .logo {  
        height: 200rpx;  
        width: 200rpx;  
        margin-top: 200rpx;  
        margin-left: auto;  
        margin-right: auto;  
        margin-bottom: 50rpx;  
    }  

    .text-area {  
        display: flex;  
        justify-content: center;  
    }  

    .title {  
        font-size: 36rpx;  
        color: #8f8f94;  
    }  
</style>

操作步骤：

直接运行实例代码

预期结果：

正常运行不报错

实际结果：

bug描述：

export default {  
        data() {  
            return {  
                title: 'Hello',  
                obj: {}  
            }  
        },  
        onLoad() {  
            this.testFun()  
        },  
        methods: {  
            testFun() {  
                this.obj = {  
                    'test.name.txt': 'frank',  
                    'test.age.num': '20'  
                }  
                setTimeout(() => {  
                    this.title = '测试'  
                    console.log(this.obj)  
                }, 100)  

            }  
        }  
    }

vue2环境运行到微信小程序，obj对象中存在test.name.txt这样的key，并且延时设置其他变量，会导致报错
Error in nextTick: "TypeError: Cannot read property 'name' of null"
