【报Bug】schema扩展ext.js引起的Unexpected token .

示例代码：

下面是查询代码

<template>  
<unicloud-db  
            ref="udb"  
            :collection="collectionList"  
            :where="where"  
            page-data="replace"  
            :orderby="orderby"  
            :getcount="true"  
            :page-size="options.pageSize"  
            :page-current="options.pageCurrent"  
            v-slot:default="{ data, pagination, loading, error, options }"  
            :options="options"  
        >  
            <view v-if="error">{{ error.message }}</view>  
            <view v-else>{{ data }}</view>  
        </unicloud-db>  
</template>  
<script>  

const db = uniCloud.database()  
const dbOrderBy = 'created_time desc' // 排序字段  
export default {  
    data() {  
        return {  
            collectionList: 'order',  
            adminVersion: version,  
            where: '',  
            orderby: dbOrderBy  
    }  
    },  
}  
</script>  

下面是schema

{  
    "bsonType": "object",  
    "required": ["create_uid", "created_time", "product_id", "date", "uid"],  
    "permission": {  
        "read": true,  
        "create": "auth.uid!=null",  
        "update": "auth.uid==doc.uid",  
        "delete": "auth.uid==doc.uid"  
    },  
    "properties": {  
        "_id": {  
            "description": "ID，系统自动生成"  
        },  
        "created_time": {  
            "bsonType": "timestamp",  
            "title": "创建时间",  
            "description": "创建时间",  
            "forceDefaultValue": {  
                "$env": "now"  
            }  
        },  
        "create_uid": {  
            "bsonType": "string",  
            "title": "创建者",  
            "forceDefaultValue": {  
                "$env": "uid"  
            }  
        },  
        "date": {  
            "bsonType": "timestamp",  
            "title": "订货日期"  
        },  
        "uid": {  
            "bsonType": "string",  
            "title": "用户",  
            "defaultValue": {  
                "$env": "uid"  
            }  
        },  
        "store_id": {  
            "bsonType": "string",  
            "title": "门店",  
            "foreignKey": "store._id",  
            "enum": {  
                "collection": "store",  
                "field": "name as text,_id as value"  
            },  
            "componentForEdit": {  
                "name": "uni-data-checkbox"  
            }  
        },  
        "state": {  
            "bsonType": "int",  
            "title": "状态",  
            "enum": [{  
                "text": "待发货",  
                "value": 0  
            }, {  
                "text": "待确认",  
                "value": 1  
            }, {  
                "text": "已完成",  
                "value": 2  
            }],  
            "defaultValue":0  
        },  
        "product_id": {  
            "bsonType": "array",  
            "title": "商品"  
        },  
        "trade_snapshot": {  
            "bsonType": "string",  
            "title": "交易快照"  
        }  
    }  
}  

操作步骤：

使用上面代码部署到线上运行

预期结果：

正常返回数据

实际结果：

报错：“Unexpected token .”
