Не удается загрузить изображение с помощью addSnapshotListener из Firestore в Android

Question

Я пытаюсь создать приложение для чата в реальном времени в Android, в моем OnCreate я смог получить все разговоры, которые я хочу, но когда я использую OnSnapShotsListener в методе OnStart, изображение в беседе не удалось загрузить, еслия не использовал OnSnapShotsListener, приложение работает хорошо, поэтому, если кто-то может помочь, я буду благодарен.я также поставил свой адаптер класса

 public class CommentAdapter extends RecyclerView.Adapter<CommentAdapter.MyViewHolder>{
        private List<Comment> commentList;
        private FirebaseFirestore nFirebaseFirestore;
        private DocumentReference nDocumentReference;

        @Override
        public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View commentView = LayoutInflater.from(parent.getContext()).inflate(R.layout.comment_view, parent, false);
            return new MyViewHolder(commentView);
        }

        @Override
        public void onBindViewHolder(final MyViewHolder holder, int position) {
            nFirebaseFirestore = FirebaseFirestore.getInstance();
            Comment comment = commentList.get(position);
            boolean isPhoto = comment.getImagePost() != null;
            if(isPhoto)
            {
                holder.textViewComment.setVisibility(View.GONE);
                holder.imageViewCommentPic.setVisibility(View.VISIBLE);
                Glide.with(CommentActivity.this).load(comment.getImagePost()).into(holder.imageViewCommentPic);
            }else{
                holder.textViewComment.setVisibility(View.VISIBLE);
                holder.imageViewCommentPic.setVisibility(View.GONE);
            }
            holder.textViewComment.setText(comment.getCommentContent());
            String id = comment.getCustomerKey();
            nDocumentReference = nFirebaseFirestore.document("Customer/"+id);
            nDocumentReference.get().addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
                @Override
                public void onSuccess(DocumentSnapshot documentSnapshot) {
                    Customer customer = documentSnapshot.toObject(Customer.class);
                    holder.textViewCustomerName.setText(customer.getName());
                    if(!(customer.getProfilePic().equals(""))) {
                        Glide.with(CommentActivity.this).load(customer.getProfilePic()).into(holder.imageViewCustomerPic);
                    }
                }
            });
        }

        @Override
        public int getItemCount() {
            return commentList.size();
        }

        public class MyViewHolder extends RecyclerView.ViewHolder{
            private TextView textViewCustomerName, textViewComment;
            private ImageView imageViewCustomerPic, imageViewCommentPic, imageViewMenuButton;

            public MyViewHolder(View view)
            {
                super(view);
                textViewCustomerName = (TextView)view.findViewById(R.id.textViewCustomerName);
                textViewComment = (TextView)view.findViewById(R.id.textViewComment);
                imageViewCustomerPic = (ImageView)view.findViewById(R.id.imageViewCustomerPic);
                imageViewCommentPic = (ImageView)view.findViewById(R.id.imageViewCommentPic);
                imageViewMenuButton = (ImageView)view.findViewById(R.id.imageViewMenuButton);
            }
        }

        public CommentAdapter(List<Comment> cList)
        {
            commentList = cList;
        }
    }

Если кто-то может помочь, я буду признателен.Ниже приведена кодировка моего
