Hi everyone! I'm currently trying to document the type of the array elements in json response. I use standalone MockMvc configuration and mock target service. The idea is to have a mechanism that alerts, if the endpoint contract has changed. One thing in that is to control changes of types.
It is not a problem to realize it against named response fields like this:

{
    person: {
        name: "some_name",
        age: 33,
        married: false,

        hobbies: ["movies", "coocking", "dancing"]
    }
}

fieldWithPath("['person']").type(JsonFieldtype.OBJECT).description(...)
fieldWithPath("['person']['name']").type(JsonFieldtype.STRING).description(...)
fieldWithPath("['person']['age']).type(JsonFieldtype.NUMBER).description(...)
fieldWithPath("['person']['married']").type(JsonFieldtype.BOOLEAN).description(...)
fieldWithPath("['person']['hobbies']").type(JsonFieldtype.ARRAY).description(...)

If someone adds a new field or delete any field in root object or in "person" object, the test will fail and enforce one to update the documentation.
The same will happen if someone changes the type of field, for ex. age: 33 -> age: "33".
The same will happen if someone changes the type of elements in "hobbies" to object like

{
    /* ... */,
    hobbies: [
    {name: "name", communitySite: "site"},
    /*...*/
    ]
}

In this case the exception will say that there are some undocumented fields in response json.

In this case the solution is in documenting like this:
fieldWithPath("['person']['hobbies'][]['name']").type(JsonFieldtype.STRING).description(...)
fieldWithPath("['person']['hobbies'][]['communitySite']").type(JsonFieldtype.STRING).description(...)

The question is how can I control the simple types of array elements in json response?
For example, if the interaction has changed and it was decided to pass not a hobbie name, but an id of hobbie. So the response will have been changed to:

{
    /* ... */,
    hobbies: [123, 91, 87]
}

In this case we surely need an exception to be thrown to be aware of need to update the text documentation.

Need some help. Thanks a lot in advance.
