Yeah, I can reproduce it, looks like the file is not actually written to the disk when playwright listens to downloads. The tests with downloads work just fine though, so it only affects manual interaction with the browser controlled by playwright.

import { test, expect } from '@playwright/test';
import fs from 'fs';

test('test', async ({ page }) => {
    const onDownloadPath = new Promise<string>(res => {
        page.on('download', dl => {
        void dl.path().then(res);
        });
    });
    await page.goto('https://clever-elion-84f381.netlify.app/');
    await page.click('a');
    const path = await onDownloadPath;
    expect(fs.readFileSync(path).toString()).toBe('{"foo":1,"bar":2}');
});
