Firebase 函数不会触发实时数据库

Question

Firebase 函数不会为实时数据库触发。它给出了 gettoken() 空指针异常。谁能告诉我这是什么意思。我在这段代码中被困了一周。它发生在我更新了所有依赖项之后。

这是我的 index.js

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
admin.initializeApp();


export const createaccount = functions.https.onCall((data) => {
 
  return admin.database().ref("/signupuser/"+data.phone).set( {
    phv: false,
    t: data.time,
    si: false,
  }).then(()=> {
    console.log("New account created");
    // const data=snapshot.data();
    // response.send(data);
    return "success";
  }).catch((error)=> {
    throw new functions.https.HttpsError("unknown", error.message, error);
  });
});

 private Task<String> addaccount(String text) {

        Log.e("check addmessage:","code is here addaccount");
        // Create the arguments to the callable function.
        Map<String, Object> data = new HashMap<>();
           data.put("phone", text);
           data.put("time", ServerValue.TIMESTAMP);
        return mFunctions
                .getHttpsCallable("createaccount")
                .call(data)
                .continueWith(new Continuation<HttpsCallableResult, String>() {
                    @NonNull
                    @Override
                    public String then(@NonNull Task<HttpsCallableResult> task) throws Exception {
                        // This continuation runs on either success or failure, but if the task
                        // has failed then getResult() will throw an Exception which will be
                        // propagated down.
                        String result = (String) task.getResult().getData();
                        assert result != null;
                        Log.e("cloud function result:",result);
                        return result;
                    }
                });
    }

'com.google.firebase.iid.internal.FirebaseInstanceIdInternal.getToken()' 当我尝试记录下面 task.getresult() 的值时发生空指针异常

 addaccount(phonenumberwithoutplus).addOnCompleteListener(new OnCompleteListener<String>() {
                            @Override
                            public void onComplete(@NonNull Task<String> task)
                            {
                                Log.e("check addmessage:","code is here complete"+task.getResult());
                                unregisterReceiver(r1);
                                if (!task.isSuccessful())
                                {
                                    Exception e = task.getException();
                                    if (e instanceof FirebaseFunctionsException)
                                    {
                                        FirebaseFunctionsException ffe = (FirebaseFunctionsException) e;
                                        FirebaseFunctionsException.Code code = ffe.getCode();
                                        Object details = ffe.getDetails();
                                        Log.e("check addmessage:","code is here"+details.toString());
                                    }
                                    registerbtn.setText("GO");
                                    progressbarregister.setVisibility(View.GONE);
                                }else
                                {
                                    Log.e("check addmessage:","code is here");
                                    readphoneverify();
                                 //   registerbtn.setText("GO");
                                 //   progressbarregister.setVisibility(View.GONE);
                                }
                            }
                        });

在我更新依赖项之前，上面的代码有效。我将所有依赖项更新到最新版本。我已经卡了一个多星期了。我不知道我哪里出错了。请有人帮我清除这个错误。
