type 类型数组 在页面v-for报错，android

你好，我根据你给出的代码做出了如下复现代码，没有发现报错

<template>  
    <scroll-view :scroll-y="true" class="home-page">  
        <scroll-view class="left-route" :scroll-y="true">  
            <view class="left-oute-item" v-for="(route,index) in routes" :key="index">  
                <text>{{route.title}}</text>  
            </view>  
        </scroll-view>  
        <scroll-view class="right-route" :scroll-y="true">  
        </scroll-view>  
    </scroll-view>  
</template>
