删除阿里云唯一索引后，还是会唯一索引冲突

删除阿里云唯一索引后，还是会唯一索引冲突

产品分类：uniCloud/支付宝小程序云

操作步骤：

1. 在云数据库创建一个document表，内容如下：

{
    "bsonType":"object",
    "required":[],
    "permission":{
        "read":false,
        "create":"auth.uid != ''",
        "update":false,
        "delete":false
    },
    "properties":{
        "_id":{
            "description":"ID，系统自动生成"
        },
        "file_path": {
            "bsonType": "sting",
            "description": "上传的文件对象"
        },
        "cloud_path": {
            "bsonType": "string",
            "description": "云端路径"
        },
        "extname": {
            "bsonType": "string",
            "description": "文件后缀"
        },
        "name": {
            "bsonType": "string",
            "description": "文件名"
        },
        "file_id": {
            "bsonType": "string",
            "description": "对象存在文件id"
        },
        "file_size": {
            "bsonType":"int",
            "description":"文件大小"
        },
        "md5": {
            "bsonType": "string",
            "description": "文件md5"
        },
        "create_by":{
            "bsonType":"string",
            "description":"创建人",
            "foreignKey":"uni-id-users._id",
            "forceDefaultValue": {
                "$env": "uid"
            }
        },
        "create_time": {
            "bsonType":"timestamp",
            "description":"创建时间",
            "forceDefaultValue": {
                "$env": "now"
            }
        }
    }
}

1. 对file_id创建一个唯一索引
2. 往里插入一段数据

{
"name": "1.png",
"extname": "png",
"file_id": "cloud://env-00jxt5rg35pe/1739622126156_0.png",
"create_by": "67b050c4c7286954d4594fb5",
"file_path": "blob:http://localhost:5174/a2da7bfa-f39e-454f-ba7f-7c0bba369a38",
"file_size": 2260511,
"cloud_path": "1739622126156_0.png",
"create_time": 1739622129122
}
