00:00.320 --> 00:02.880
In this video we will fix the bug.

00:02.920 --> 00:05.800
Belong to the same method.

00:06.080 --> 00:08.320
Okay, right here in preview.

00:08.720 --> 00:10.480
I already got a bit for you.

00:10.520 --> 00:14.080
We need to file the message if it already seen.

00:15.000 --> 00:18.000
If it not seen, we need to handle right?

00:18.440 --> 00:21.360
And from right now we need to change a little bit.

00:21.760 --> 00:29.160
Firstly we will got the user right and we need to view the file one and update.

00:29.680 --> 00:33.280
We will file by the ID over here okay.

00:33.440 --> 00:34.960
By the message adding over here.

00:35.280 --> 00:41.840
And we need to add to set operator and put the user back to the symbol okay.

00:41.880 --> 00:47.720
Because right now we we want to ensure it no duplicate right here.

00:47.720 --> 00:56.080
It also ensure it not duplicate but it not good for the parallel okay.

00:56.360 --> 01:05.840
When we send the two two API at the same time okay we will got the some issue with this approach.

01:06.720 --> 01:07.200
Okay.

01:07.240 --> 01:11.080
We will got some recognition with this approach for one reason.

01:11.080 --> 01:15.240
We need to change this behavior into the update.

01:15.680 --> 01:21.100
Sorry into the atomic operator will be the file file one and update.

01:21.580 --> 01:22.100
Okay.

01:22.340 --> 01:28.700
Please hold here and make sure we return the new update document and also populate if you want.

01:29.100 --> 01:29.580
Right.

01:30.340 --> 01:33.420
And also we need to find the message over here.

01:33.700 --> 01:34.540
Check the message.

01:35.020 --> 01:45.300
And right now what we want to do right now is we need to check if the user just received by okay.

01:47.020 --> 01:52.780
And if the user already inside the scene by we need to skip that.

01:52.820 --> 01:54.820
We will not do anything.

01:56.260 --> 01:56.780
Okay.

01:58.340 --> 02:04.180
So it means if the user already inside the scene by.

02:11.940 --> 02:12.300
Okay.

02:12.340 --> 02:19.620
For example I, I already seen we will not do anything okay.

02:20.660 --> 02:25.460
So make sure you know bit about us.

02:25.660 --> 02:30.500
And right now you need to jump form a little line user.

02:32.140 --> 02:32.860
Thus for the.
