我正在使用 volley JSONrequest 从我的 android 应用程序向 ESP32 服务器发送 Wifi 凭据。我能够在 ESP32 服务器中获取请求，但在发送响应后，我在 volley 中收到了 VolleyError。我在其他任何地方都找不到这个错误。

org.json.JSONException: Value Deregistered of type java.lang.String cannot be converted to JSONObject

这是我的代码：

JSONObject jsonBody = new JSONObject();
jsonBody.put("ssid", ssid);
jsonBody.put("password", password);
jsonBody.put("fbtoken", FirebaseInstanceId.getInstance().getToken());
jsonBody.put("uid", anonUser.getUid());
       
Log.d("WifiCredential", "Post: "+jsonBody.toString());
JsonObjectRequest credetialPost = new JsonObjectRequest
(Request.Method.POST, URL, jsonBody, new Response.Listener<JSONObject>() {

      @Override
      public void onResponse(JSONObject response) {

          try {

              boolean connected = response.getBoolean("connected");
              if (connected){
                  debugRef.child("CredSend").child("Connected").setValue(true);
                  LAN_IP = response.getString("ip");
                  Log.d("WifiCredential", "Connected: "+LAN_IP);
                  Toast.makeText(MainActivity.this,"LAN Connected",Toast.LENGTH_LONG).show();     
                  }
              } catch (JSONException e) {
                            Log.d("WifiCredential", "JSON Error: " + e.getMessage());
                            Log.d("WifiCredential", "Response: "+response);
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        // TODO: Handle error
                        Log.d("WifiCredential", "Error Last: "+Objects.requireNonNull(error.getMessage()));
                   
                    }
                });

        credetialPost.setRetryPolicy(new DefaultRetryPolicy(
                10000,
                1,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

        requestQueue.add(credetialPost);

我server.send(200, "application/json", "{\"connected\":\"True\"}");从 ESP32 发送。
