Rest Assured extracting and mapping complex object

I am writing test cases with rest assured and gauge. I can not fix the response parsing when it comes to complex objects (with List it works well). I have the following structures:

public class SearchResult {

 private List<T> pageEntries;
 private long totalCount;
 private long size;

}

The endpoint waits SearchResult

JSON received: "pageEntries": [ { "id": "12345", "name": "VpfIRPxVNHHYfTRPAgZDBstgFIqMtubBUpClnhlwJRQZWpkWlOzEKkrYZXRgdFbtoe", } ], "totalCount": 1, "size": 1 }

I saved the response into gauge datastore as Searchresult object but the type of pageEntries is a LinkedHashmap and not DummyResult as expected.

 @Step("Save result as <storeKey>")
 public void saveResultX(final String storeKey) {
 final Class className = (Class) suiteDataStore.get(RESPONSE_CLASS);
 saveDTO(className, storeKey);
 final SearchResult dto = (SearchResult) suiteDataStore.get(storeKey);
 log.info(dto.getPageEntries().get(0).getClass().getName());
 }

and I got java.util.LinkedHashMap ....

Any idea how to map the DummyResult class from response (without extracting extract().path("pageEntries")?
