uni-app x无法编译Android？

这样，缺少函数的返回值定义

<template>  
    <view>  
        <text>item-{{item}}</text>  
    </view>  
    <view>  
        <text>attr-{{getAttr}}</text>  
    </view>  
</template>  

<script setup lang="uts">  
    const props = defineProps({  
        item: {  
            type: Object as PropType<UTSJSONObject>,  
            required: true  
        }  
    })  
    const getAttr = computed(():string => {  
        let item = props.item  
        let name = item.getString('name')  
        if (name == null) {  
            return 'not found'  
        }  
        return name  
    })  
</script>
