Getting an error using restassured and testng. java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class org.hamcrest.Matcher

Question

Hi I've been using these Json paths in the past but for some reason I've encountered an issue I can't seem to solve. I think it is something to do with my response having an array? Now when I tried yesterday I got a strange response which I'm no longer getting I'm now getting an error.

java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class org.hamcrest.Matcher (java.util.ArrayList is in module java.base of loader 'bootstrap'; org.hamcrest.Matcher is in unnamed module of loader 'app')

    package skySportsPages;
import static io.restassured.RestAssured.*;
import static org.hamcrest.Matchers.*;
import io.restassured.http.ContentType;
import io.restassured.path.json.JsonPath;
import org.testng.annotations.Test;
import java.io.File;

public class test extends enablers {


    @Test
    public void GetArticlesJson() {

        JsonPath expectedJson = new JsonPath(new File("src/test/java/jsonFiles/articles.json"));

        given().
                when().
                get(allArticles).
                then().
                assertThat().
                contentType(ContentType.JSON).
                and().
                body("", hasItem(expectedJson.get("")));


    }

}
