java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.testing.models.Account

I'm getting below error:

java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.testing.models.Account

with below code

final int expectedId = 1;

Club newClub = create();

int expectedResponseCode = Response.SC_OK;

ArrayList<Account> account = given().when().expect().statusCode(expectedResponseCode)
    .get("accounts/" + newClub.getOwner().getCustId() + "/clubs")
    .as(ArrayList.class);
assertThat(account.get(0).getId()).isEqualTo(expectedId);

Is there a reason why I cannot do get(0)?

When I do .size() it shows the entry and output is there.
