After adding 2 pages, pre-rendering is getting stuck

[saiy2k]

So I added 2 new routes and pages:

app-root.tsx:

renderRouter() {
        ...
          <ion-route url="/about" component="tab-about"></ion-route>
        </ion-route>

+        <ion-route url="/render-list" component="page-render-list"></ion-route>
+        <ion-route url="/render-detail/:renderId" component="page-render-detail"></ion-route>
        <ion-route url="/tutorial" component="page-tutorial"></ion-route>
        <ion-route url="/login" component="page-login"></ion-route>
        <ion-route url="/account" component="page-account"></ion-route>
        ...
}

render() {
              ...
              <ion-list lines="none">
                <ion-list-header>Account</ion-list-header>

+                <ion-menu-toggle autoHide={false}>
+                    <ion-item detail={false} href="/render-list" class={{ 'selected': this.isActiveUrl('/render-list') }}>
+                    <ion-icon slot="start" name="help"></ion-icon>
+                    <ion-label>Render List</ion-label>
+                  </ion-item>
+                </ion-menu-toggle>

                <ion-menu-toggle autoHide={false}>
                  {this.loggedIn ? (
                    <ion-item detail={false} href="account" class={{ 'selected': this.isActiveUrl('/account') }}>
                    ...
}

where, page-render-list is an exact replica of page-speaker-list, except for following change:

                      <ion-item detail={false} lines="none" class="speaker-item" href={`/**render-detail**/${speaker.id}`}>

and page-render-detail is an exact replica of `page-speaker-detail, except for:

  @Prop() **renderId**: string;
  async componentWillLoad() {
    this.speaker = await ConferenceData.getSpeaker(this.**renderId**);
  }

Basically I replicated speaker list and detail page, but made them linked for side menu and not part of the tabs.

With these changes, the live serve is working fine. But the pre-rendering is getting stuck. Here is my log with verbose flag:

[ ~/projects/gr/stencilconf ]$ npm run build --prerender --verbose
