Angular swiper gives error when compiling error TS2430: Interface 'SwiperContainerEventMap' incorrectly extends interface 'HTMLElementEventMap'

1. I want to use swiper version 9.3.0 for angular version 15.2.8 and install swiper using npm i swiper
2. As per the guide of new swiper elements web-components I follow this guide to register swiper with angular.

// import function to register Swiper custom elements
import { register } from 'swiper/element/bundle';
// register Swiper custom elements
register();

Then, I am running angular command ng serve -o but compilation failed and gives error like below

error TS2430: Interface 'SwiperContainerEventMap' incorrectly extends interface 'HTMLElementEventMap'. 
  Types of property '"click"' are incompatible.
    Type 'CustomEvent<any>' is missing the following properties from type 'MouseEvent': altKey, button, buttons, clientX, and 20 more.

6 interface SwiperContainerEventMap extends HTMLElementEventMap {

I have added schemas inside app.module.ts file too.

@NgModule({
  schemas: [CUSTOM_ELEMENTS_SCHEMA],

Here is official guide

How to solve this problem? Thanks.

We had the same issue.
According to github swiper issues (https://github.com/nolimits4web/swiper/issues/6657) it us caused due to the combination of the latest versions of Angular, Typescript and swiper.

We managed to solve this by downgrading our package.json.
