无法将数据保存到FiRecovery

Question

这是使用电子邮件密码注册帐户的所有代码，保存验证电子邮件，将用户数据保存到Firestore数据库中。只有Firestore数据库无法运行。

fAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
    @Override
    public void onComplete(@NonNull Task<AuthResult> task) {
        if(task.isSuccessful()){

            // send verification link

            FirebaseUser fuser = fAuth.getCurrentUser();
            fuser.sendEmailVerification().addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    Toast.makeText(register.this, "Verification Email Has been Sent.", Toast.LENGTH_SHORT).show();
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.d(TAG, "onFailure: Email not sent " + e.getMessage());
                }
            });

            Toast.makeText(register.this, "User Created.", Toast.LENGTH_SHORT).show();
            userID = fAuth.getCurrentUser().getUid();
            DocumentReference documentReference = fStore.collection("users").document(userID);
            Map<String,Object> user = new HashMap<>();
            user.put("fName",fullName);
            user.put("email",email);
            user.put("phone",phone);
            documentReference.set(user).addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    Log.d(TAG, "onSuccess: user Profile is created for "+ userID);
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.w(TAG, "onFailure: " + e.toString());
                }
            });
            startActivity(new Intent(getApplicationContext(),MainActivity.class));

        }
        

else { Toast.makeText（register.this， “Error ！ ” task.getException（）.getMessage（）， Toast.LENGTH_SHORT）.show（）;progressBar.setVisibility（View.GONE）;} } });} });
