# Search for changes to the acl field of the Data Item - Index Data Item interface
### Details
In order to better protect the data security of your imported data in Feishu Open Search, we will upgrade the index data item interface of the open platform. The acl parameter of this interface will be set as a required parameter, and the imported data will not be visible by default.

Take effect along with version update：No<br>
Effective upon：- <br>
Effective date：2022-1-23<br>

### Impacts
If you fail to adjust the request parameters of the interface in time, the following problems will occur after the interface is upgraded:
1. If the interface request body does not contain the acl field, the interface will return an error;
2. If the acl field in the interface request body is an empty array, the visibility of the data will change from "visible to all" to "invisible to all".

### How to adapt to the change
1. If your request body contains the acl field, and the acl field is not an empty array, you can ignore this push;
2. If your request body does not contain the acl field, or the acl is an empty array, please adjust the request body and explicitly configure it as "visible to all members". An example is as follows:
{
    “acl”:[{
        “access”:“allow”,
        “type”:“user”,
        “value”:“everyone”
    }]
}
