The default addition of "aggs": {} causes scroll pagination invalid

@Nick-S-2018 is already working on this.

Since Aug 25, 2025.

sdk version: 8.1.0
```java
/**
* search
*/
public SearchResponse search(String tableName, String queryString, List sort, String scrollToken,
Integer size) {
ApiClient client = this.newClient();

SearchQuery searchQuery = new SearchQuery();
searchQuery.setQueryString(queryString);

SearchRequest searchRequest = new SearchRequest();
searchRequest.table(tableName).query(searchQuery);
searchRequest.sort(sort);
searchRequest.limit(size);

// scroll pagination
Map options = new HashMap<>();
if (StrUtil.isNotBlank(scrollToken)) {
options.put("scroll", scrollToken);
} else {
options.put("scroll", true);
}
searchRequest.options(options);

SearchApi searchApi = new SearchApi(client);

try {
SearchResponse response = searchApi.search(searchRequest);
log.debug("Search response: {}", response);
return response;
} catch (ApiException e) {
this.printError(e);
throw new RuntimeException(e);
}
}
```

final json body:
```json
{
"table": "products",
"query": {
"query_string": "黑色"
},
"join": [],
"limit": 10,
"aggs": {},
"expressions": {},
"options": {
"scroll": "eyJvcmRlcl9ieV9zdHIiOiJzYWxlcyBhc2MsIGlkIGFzYyIsIm9yZGVyX2J5IjpbeyJhdHRyIjoic2FsZXMiLCJkZXNjIjpmYWxzZSwidmFsdWUiOjAsInR5cGUiOiJpbnQifSx7ImF0dHIiOiJpZCIsImRlc2MiOmZhbHNlLCJ2YWx1ZSI6MjMwOTE4NDQwMzM3NDM0MjE1MywidHlwZSI6ImludCJ9XX0="
},
"sort": [
{
"sales": {
"order": "asc"
}
},
{
"id": {
"order": "asc"
}
}
]
}
```

There is an `"aggs": {}`, is auto-generated, it will cause scroll pagination invalid.
Did I use it incorrectly, or is this a feature or a bug ?
