Unit Test Spring MVC Rest Service: array jsonPath

In my Spring controller I have a method that returns the following json:

[
  {
    "id": 2,
    "dto": null,
    "user": {
      "userId": 2,
      "firstName": "Some",
      "lastName": "Name",
      "age": 100,
      "aboutMe": "boring"
    },
    "isYoung": false,
    "isOk": false
  }
]

I'm trying to write a test for this getter.Here is my test:

@Test
public void getterMethod() throws Exception{
    mockMvc.perform(get("/path?id=1")).andExpect(status().isOk())
        .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
        .andExpect(jsonPath("$[0].id", is(2)))
        .andExpect(jsonPath("$[2].user.userId", is(2)))
        .andExpect(jsonPath("$[2].user.firstName", is("Giorgos")))
        .andExpect(jsonPath("$[2].user.lastName", is("Ant")))
        .andExpect(jsonPath("$[3].isYoung", is(false)))
        .andExpect(jsonPath("$[4].isOk", is(false)));
}

Apparently I'm not getting this right:

Although if I run the test only for the $[0].id the test passes. However for all the rest cases (for the nested user object and isYoung fiels and isOk) I'm getting an array index exception error.

Any ideas?Thanks!

Should the test be:

@Test
public void getterMethod() throws Exception{
    mockMvc.perform(get("/path?id=1")).andExpect(status().isOk())
        .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
        .andExpect(jsonPath("$[0].id", is(2)))
        .andExpect(jsonPath("$[0].user.userId", is(2)))
        .andExpect(jsonPath("$[0].user.firstName", is("Some")))
        .andExpect(jsonPath("$[0].user.lastName", is("Name")))
        .andExpect(jsonPath("$[0].isYoung", is(false)))
        .andExpect(jsonPath("$[0].isOk", is(false)));
}
