Lighthouse report is blank, and I can only see a console error

[potnoddle]

I'm running my report in Playwright Test Runner with vscode, I did have the code running, but it no longer works. And I've run this against multiple sites without luck.

lighthouseVersion: 11.7.1

I have updated to the latest version, which may have broken it.

I hit this issue as well with playwright-lighthouse 4.0.0, playwright 1.46.1 and lighthouse 12.2.1.

Took me a while to figure out what was going on. It should be reproducible if you don't set thresholds for any category.

This playwrightLighthouseConfig produced the above error:

const playwrightLighthouseConfig = {
    ignoreError: true,
    reports: {
        formats: {
            json: true,
            html: true,
            csv: true,
        },
        name: 'lighthouse-default-report',
        directory: `${process.cwd()}/lighthouse-report`
    },
    port: 9222,
    thresholds: {}
};

and this one works:

const playwrightLighthouseConfig = {
    ignoreError: true,
    reports: {
        formats: {
            json: true,
            html: true,
            csv: true,
        },
        name: 'lighthouse-default-report',
        directory: `${process.cwd()}/lighthouse-report`
    },
    port: 9222,
    thresholds: {
      performance: 0
    }
};

Note: I'm setting IgnoreError so I can get the report back regardless of whether there's a failure so I can make custom reports before re-throwing the error. I don't think its related to the problem but also didn't investigate.
