Question

core.js:4442 ERROR TypeError: Cannot read property 'name' of null

    setTimeout(() => {
        this.userDetails = this.cacheService.getUser();
            this.userName = this.userDetails.name;
          }, 1000);

Answer 1

it means that the object "userDetails" is equal to null so you can't get the property "name" out of it, you must first make sure "userDetails" was assigned a value like:

this.userDetails.name= "Jhon Doe"

Answer 2

Try to set your script at the bottom of your.HTML page
