Angular Material Migration to 15 - MatButton and MatIconButton

Question

After Angular Material Migration from 14 to 15 this error appears:

Error: NG0300: Multiple components match node with tagname button: MatButton and MatIconButton

Ideas how this can be fixed?

Answer 1

The reason was using mat-button and mat-icon-button on same element

<button [matMenuTriggerFor]="menu" mat-button mat-icon-button>

To resolve this just use only one.
