NG8001: 'mat-chip-list' is not a known element - Angular 19

I created a Test Component to check if angular material 19.0.0 supports mat-chip-list.
test-chips.component.ts:

import { Component } from '@angular/core';
import { MatChipsModule } from '@angular/material/chips';

@Component({
  selector: 'app-test-chips',
  standalone: true,
  imports: [MatChipsModule],
  template: `
    <mat-chip-list aria-label="Fish selection">
      <mat-chip>One fish</mat-chip>
      <mat-chip>Two fish</mat-chip>
      <mat-chip color="primary" selected>Primary fish</mat-chip>
    </mat-chip-list>
  `
})
export class TestChipsComponent { }

But it is returning error shown below:

[ERROR] NG8001: 'mat-chip-list' is not a known element.

My package.json:

  "name": "complexclaims",
  "version": "0.0.1",
  "scripts": {
    "ng": "ng",

  }
}

Is it a bug in angular material 19?

Solution

  • The element attribute has changed. Please update mat-chip-list to mat-chip-set.
