How to solve Retrofit Bad Request error when posting data

I am having a problem executing a post request using Retrofit. I keep getting the Bad Request error log response.message()

This is the response from Postman GET request to my API:

{
    "data": [
        {
            "id": 7,
            "attributes": {
                "createdAt": "2022-09-14T17:10:38.806Z",
                "updatedAt": "2022-09-14T17:10:38.806Z",
                "publishedAt": "2022-09-14T17:10:38.767Z",
                "title": "This is title",
                "body": "This is body"
            }
        }
    ],
    "meta": {
        "pagination": {
            "page": 1,
            "pageSize": 25,
            "pageCount": 1,
            "total": 1
        }
    }
}

I am able to perform the Retrofit GET and DELETE. The problem comes when am trying to execute a POST. This is the request body that is send using Postman and it is working correctly:

{
    "data": {
        "title": "This is title",
        "body": "This is body"
    }
}

How can I replicate this request body to make POST request using Retrofit using Android Java? Here is the code am using which is retuning Bad request error:

My interface:

public interface Service {

    @FormUrlEncoded
    @POST("api/notes")
    Call<DataResponse> create(
            @Field("title") String title,
            @Field("body") String body
    );

The method I am excuting to Post data:

    private void create(){
        //Call the interface
        crudInterface = RestClient.connection().create(Service.class);
        Call<DataResponse> call = crudInterface.create(title, body);
        call.enqueue(new Callback<DataResponse>() {
            @Override
            public void onResponse(@NonNull Call<DataResponse> call, @NonNull Response<DataResponse> response) {
                Toast toast = Toast.makeText(getApplicationContext(), response.message(), Toast.LENGTH_LONG);
                toast.show();
                Log.e("Response : ", response.message());
                Log.d("Response code: ", String.valueOf(response.code()));

            }

            @Override
            public void onFailure(@NonNull Call<DataResponse> call, @NonNull Throwable t) {
                Toast.makeText(getApplicationContext(), "Gagal menghubungi server : "+t.getMessage(), Toast.LENGTH_LONG).show();
                Log.e("Throw err: ",t.getMessage());
            }
        });
    }

I get this to my logcat:

2022-09-14 20:20:33.153 9649-9649/com.application.strapi_crud E/Response :: Bad Request
2022-09-14 20:20:33.252 9649-9649/com.application.strapi_crud D/Response code :: 400

Data class:

public class Data{
    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("body")
    @Expose
    private String body;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }
}

Then:

public class Notes {

    @SerializedName("id")
    private int id;
    @SerializedName("attributes")
    private Data data;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Data getAttribute() {
        return data;
    }

    public void setAttribute(Data attribute) {
        this.data = data;
    }

    public void setAttribute(String title, String body) {

    }
}

Finally the DataResponse:

public class DataResponse {

    @SerializedName("data")
    @Expose
    private List<Notes> data = null;

    public List<Notes> getData() {
        return data;
    }

    public void setData(List<Notes> data) {
        this.data = data;
    }
}
