android - 尝试更新文档时 Firestore (0.6.6-dev) 出现内部错误

Question

下面的错误让我很为难。我正在尝试更新存储在我的 Firestore 项目中的文档中的单个字段。

这是我的代码:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

if(user == null){
    Log.e(LOGTAG, "Could not upload because user is not logged in.");
    return;
}

FirebaseFirestore db = FirebaseFirestore.getInstance();
DocumentReference userRef = db.collection("users").document(user.getUid());

TextInputEditText textview = findViewById(R.id.edit_text_foo);
String enteredText = textview.getText().toString(); //implements CharSequence, thus toString() gives the correct string
userRef.update("field_foo", enteredText)
        .addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) {
                Log.i(LOGTAG, "Text successfully updated!");
            }
        })
        .addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.w(TAG, "Error updating text", e);
            }
        });

每次执行该方法时都会出现错误。恕我直言，“内部错误”短语可能表明这确实是 Firestore 数据库的早期测试状态带来的问题。但是，这是我的第一个 android 应用程序，我也是 Firebase 的新手。任何合格的估值、任何解决方案的想法或任何指示？

感谢@hatboysam，它现在可以使用了。解决方案尽可能简单:

清除设备上应用程序管理器中的数据。

然后再次运行该应用。
