“NullInjectorError: No provider for Overlay!” in console (Angular Material)

Question

I\'m getting an error when using Angular Material. Specifically,

ERROR Error: Uncaught (in promise): Error:
StaticInjectorError(AppModule)[CdkConnectedOverlay -&         


        

Answer 1

I was getting the exact same error, due to lazy loaded modules which had the mat-menu component in them.

What removed the error for me, was including MatDialogModule and MatMenuModule in the AppModule, which isn't lazy-loaded:

import { MatDialogModule } from '@angular/material/dialog';
import { MatMenuModule } from '@angular/material/menu';

Then the error was gone, and the mat-menu worked again
