Dear Othmane Abouelyzza,
Thanks for taking the time to read our post and for reaching out to us.
There could be multiple of reasons why this has happened. We can think of 3 possible reasons which could be the cause of your problem:
- Perhaps you haven’t imported ItemsModule in the AppModule
- Maybe you forgot to import Items in ItemsModule or
- There’s possibly a mismatch between the imported class and the actual class name.
Perhaps you could provide snippets of your code so we can better help you :)
Thanks again and stay safe!
