Redux how to read nested object property?

Question

Iron

good afternoon, there is an object of the view

{
  "id": 6,
  "leadcreatedate": "0001-01-01T00:00:00Z",
  "leadmodifydate": "0001-01-01T00:00:00Z",
  "utm": {
    "uid": {
      "Int64": 1,
      "Valid": true
    },
    "domainsource": {
      "String": "http://site.ru",
      "Valid": true
    },
    "urlsource": {
      "String": "http://site.ru",
      "Valid": true
    }
   
  }
}

In the stateStore, I see all the data, everything is written perfectly, but I can’t read the nested UTM object
this.props.test.utm - outputs an object with data
this.props.test.utm.uid to the console - TypeError: Cannot read property 'uid' of undefined
What am I doing wrong?

Answer 1

Радиатор видео горячий - держать палец невозможно

Это перегрев — чистите вентилятор, уберите программы "оптимизации" охлаждения или соответствующие настройки в драйвере (BIOS видео тоже) приведите в состояние по-умолчанию..

Answer 2

Perhaps you are trying to read it before the data has arrived (on the first render), you can make a condition - if such an object exists - output the data.
This happens when you make a request to the server in the componentDidMount method, the render has already worked, and you only requested the data after that. Then the data will be received, the props will be updated, the second render will be called already with the data.
