UnityWebRequest.Put() not working for Play/Resume EndPoint. Error 400 Malformed JSON

[dassoop]

The UnityWebRequest.Put() works fine for the Pause EndPoint but not the Play/Resume. I am not passing any body data for either of these calls. No context_uri and no uri.

`public void PlayButtonRequest()
    {
        UnityWebRequest www = UnityWebRequest.Put("https://api.spotify.com/v1/me/player/play", "bodyData");
        www.SetRequestHeader("Authorization", "Bearer " + accessToken);
        www.SetRequestHeader("Content-Type", "application/json");
        www.SetRequestHeader("Accept", "application/json");
        StartCoroutine(PlayButtonResponse(www));
    }

    IEnumerator PlayButtonResponse(UnityWebRequest www)
    {
        yield return www.SendWebRequest();

        if (www.isNetworkError)
        {
            Debug.Log(www.error);
        }

        else
        {
            Debug.Log(www.downloadHandler.text);
        }
    }`
