I got this error message “ERROR Error [NullInjectorError]: R3InjectorError(Environment Injector)[_HttpClient -> _HttpClient]:
NullInjectorError: No provider for _HttpClient!” while trying to upload and save gifs through backend, nd there are some settings that I get from the backend of my application.

My component display users’attributes (name, email, …).
I would like to display labels without waiting for their value. I found a solution but I don’t like it because I repeat <span *ngIf="user">.
