Com.android.volley.ParseError: org.json.JSONException: значение New типа java.lang.String невозможно преобразовать в JSO ⇐ Android

[Гость]

Working on Android Studio and IntelliJ for mobile dev, and when working on a signup page, after sending the request I get this error

com.android.volley.ParseError: org.json.JSONException: Value New of type java.lang.String cannot be converted to JSONObject but the issue is that i can see on the backend that it is saving the user and giving a 200 OK response

POST "/people", parameters={} Mapped to coms309.people.PeopleController#createPerson(Person) Read "application/json;charset=utf-8" to [5 dave borucki [email protected] dunk] 5 dave borucki [email protected] dunk Using 'text/plain', given [*/*] and supported [text/plain, */*, application/json, application/*+json] Writing ["New person dave Saved"] Completed 200 OK This is what my AS frontend code looks like.
