I am using MDB Angular Pro version facing issue in Stepper

I have faced below error

error NG8002: 0mCan't bind to 'vertical' since it isn't a known property of 'mdb-stepper'. If 'mdb-stepper' is an Angular component and it has 'vertical' input, then verify that it is part of this module. If 'mdb-stepper' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

Code :

import { MDBSpinningPreloader, MDBBootstrapModulesPro, ToastModule } from 'ng-uikit-pro-standard';

imports:

[ BrowserModule, BrowserAnimationsModule, AppRoutingModule, FormsModule, ReactiveFormsModule, HttpClientModule, ColorPickerModule, ToastModule.forRoot(), MDBBootstrapModulesPro.forRoot(), ],

providers: [ MDBSpinningPreloader, { provide: HTTP_INTERCEPTORS, useClass: JwtInterceptor, multi: true }, { provide: HTTP_INTERCEPTORS, useClass: ErrorInterceptor, multi: true } ],

schemas: [ NO_ERRORS_SCHEMA, CUSTOM_ELEMENTS_SCHEMA ],

bootstrap: [AppComponent] }) export class AppModule { }
