Step 1. Enable playwright json report if you haven't

export default defineConfig({
    testDir: './tests',
    retries: 0,
    reporter: [
        ['json', { outputFile: './reports/report.json' }]
    ],
    use: {
        trace: 'retain-on-failure',
        screenshot: 'only-on-failure',
    },
    outputDir: './traces',
    projects: [
        {
        name: 'chromium',
        use: { ...devices['Desktop Chrome'] }
        }
    ]
    });
