Referenced ionicon not found 404

Hi, I’m new to Ionic and trying to implement it into an angular project. For some reason I cannot use ionicons, it just keeps giving me a 404. I’m using Ionic 6.5.0:

Simple page:

  <ion-tab-bar slot="top">
    <ion-tab-button tab="user">
      <ion-icon name="people-outline"></ion-icon>

The tab bar is created, with only the text “user” and if I look in the developer console I get this error:

GET http://localhost:4200/svg/people-outline.svg 404 (Not Found)

What am I missing here?

Hi, you can check the angular.json configuration file, it should have the following settings:

This settings is mandatory in order to make the ionicon work properly.

Also, if you using pnpm instead of npm, the ionicons package should be installed as a dependency:
