Why is this error thrown from core js?

Question

Angular

There is such an error:


In general, there is a directory, there are three posts in it, when you click on the post, it opens, I transfer the object to it. In the console, you can see that I received the object and displayed the title of the object. As you can see, it is displayed, but at the same time, core js swears. The first time I encountered this error. Can someone tell me how to get rid of it? And why did she show up?

Answer 1

Most likely in the template you are accessing the name field of an object that has not yet loaded.
Hide the entire block under *ngIfor put questions in the template, such as{{obj?.name}}
