7 00:00:23,460 --> 00:00:24,840 Well, how something went wrong? 8 00:00:25,020 --> 00:00:25,860 Try again later. 9 00:00:26,120 --> 00:00:31,110 And again, the response is 500, because we're not checking more up in the error handler. 10 00:00:31,410 --> 00:00:33,440 So let's navigate back on. 11 00:00:33,670 --> 00:00:39,570 I'm fully aware that some people might find this annoying, but in my case, I will uncomment my entire 12 00:00:39,570 --> 00:00:43,380 error response and I'll comment out of the default error. 13 00:00:43,710 --> 00:00:47,820 And don't worry, we won't be doing that in every video Charlotte mission back. 14 00:00:48,150 --> 00:00:55,620 And what you'll notice is the error object or in this case, there is a cold property. 15 00:00:56,250 --> 00:00:57,990 So this is what we're getting back. 16 00:00:58,470 --> 00:01:04,050 We're getting back a error object with a cold property, and the value is this one. 17 00:01:04,290 --> 00:01:06,990 So we have one one and then three zeroes. 18 00:01:07,440 --> 00:01:09,270 So when it comes to our condition. 19 00:01:10,280 --> 00:01:16,280 We'll actually check for the cold property and whether the value is equal to this. 20 00:01:17,150 --> 00:01:24,470 Now that's going to be the condition inside of the condition instead of object values will use object 21 00:01:24,470 --> 00:01:28,910 keys and we'll pass in the error and then key value. 22 00:01:29,300 --> 00:01:31,490 So this is going to be an object. 23 00:01:32,180 --> 00:01:33,190 I'm in there. 24 00:01:33,200 --> 00:01:40,160 I just want to access the properties that the object has because I want to send back such and such property 25 00:01:40,400 --> 00:01:44,720 has to be unique and you'll see what I'm talking about in a second. 26 00:01:45,140 --> 00:01:54,200 And just like with object values, if you need a refresher on object keys, the Amdocs is a very good 27 00:01:54,200 --> 00:01:55,070 place to start. 28 00:01:55,280 --> 00:01:56,800 So let's navigate back. 29 00:01:56,810 --> 00:02:02,260 And like I said, the first thing we want to do is to set up the condition where again, there is a 30 00:02:02,270 --> 00:02:04,880 our object now inside of that object. 31 00:02:05,120 --> 00:02:11,930 There might be a cold property and if it exists, but I want to check whether the value for that property 32 00:02:12,140 --> 00:02:14,450 is 11 and nine three zero. 33 00:02:14,480 --> 00:02:16,400 So let's go here with our code. 34 00:02:16,790 --> 00:02:21,890 And if that is equal to one one one nine three zero there, this is the case. 35 00:02:22,250 --> 00:02:28,190 Well, first again, let's set up the proper status code, which is going to be for honor like so. 36 00:02:28,580 --> 00:02:31,130 So in this case, we can just copy and paste. 37 00:02:31,460 --> 00:02:34,490 And then the second thing, let's set up the message. 38 00:02:34,700 --> 00:02:38,410 So say here, default error and message is equal to. 39 00:02:38,750 --> 00:02:42,020 Now first, I want to set up the template string that's number one. 40 00:02:42,260 --> 00:02:46,100 And then I'll say field has to be unique. 41 00:02:46,250 --> 00:02:47,660 Now which field am I talking on? 42 00:02:47,930 --> 00:02:52,390 Well, like I said, we'll use object keys and not to do that. 43 00:02:52,410 --> 00:03:00,260 We'll have to set up our interpolation here and we'll use object van keys and then let's pass in the 44 00:03:00,260 --> 00:03:00,650 error. 45 00:03:00,950 --> 00:03:04,040 That's the entire object that we have. 46 00:03:04,430 --> 00:03:08,180 And more specifically, I'm looking for this key value. 47 00:03:08,540 --> 00:03:15,200 So let's go here and let's say key and value, that's the object that I want to pass in. 48 00:03:15,560 --> 00:03:20,780 And once I save it, you'll notice if we go back to the post mount and if we send. 49 00:03:21,050 --> 00:03:26,930 And of course, nothing changed because I should comment on the first one and then I'll come on the 50 00:03:26,930 --> 00:03:33,750 second one where we have the default error message and now you'll notice the email field has to be unique. 51 00:03:33,870 --> 00:03:35,930 Now there is a space missing. 52 00:03:36,680 --> 00:03:39,950 So once we add this one, everything should be correct. 53 00:03:40,190 --> 00:03:47,120 So if the user is going to try to register with an email that is already in use, then we'll send back 54 00:03:47,120 --> 00:03:51,620 the 4hana response with the message email field has to be unique.
