Pixi JS 7 / Error on PIXI.Assets.load(json) - 2d

Question

i take this code from Pixi examples ( https://pixijs.io/examples/?v=dev#/sprite/animatedsprite-jet.js ) :
import * as PIXI from 'pixi.js';
import json from './assets/fighter.json';
const app = new PIXI.Application({ background: '#1099bb' });
document.body.appendChild(app.view);
PIXI.Assets.load(json).then(() => {
// create an array of textures from an image path
const frames = [];
for (let i = 0; i < 30; i++) {
const val = i < 10 ? `0${i}` : i;
// magically works since the spritesheet was loaded with the pixi loader
frames.push(PIXI.Texture.from(`rollSequence00${val}.png`));
}
// create an AnimatedSprite (brings back memories from the days of Flash, right ?)
const anim = new PIXI.AnimatedSprite(frames);
/*
* An AnimatedSprite inherits all the properties of a PIXI sprite
* so you can change its position, its anchor, mask it, etc
*/
anim.x = app.screen.width / 2;
anim.y = app.screen.height / 2;
anim.anchor.set(0.5);
anim.animationSpeed = 0.5;
anim.play();
app.stage.addChild(anim);
// Animate the rotation
app.ticker.add(() => {
anim.rotation += 0.01;
});
});
And in browser console i'm get this message :
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'split')

I'm using a Vite(4.0)
I try using path to JSON in PIXI.Assets.load('/assets/fighter.json), is not help me.
But i'm get another message in browser console :
