Ok I've worked out what the problem is. I was running accessibility only with

    lighthouseOptions: {
        onlyCategories: ['accessibility'],
    }

Removing this or adding performance fixes the issue, so I assume the images are generated in that stage?!

I'm also having this issue when running the scan with only the accessibility category enabled + generating a static report.

I've noticed that the static files are looking for an image file called screenshot.jpeg but the static files only include an image file called full-screenshot.jpeg in the report directory for a specific page. The __screenshot-thumbnails__ directory is empty.

Hi, thanks for the issue, I've pushed up a fix in v0.14.0.
