Hey @bux & @thomasbnt

Thanks for reporting this issue. Looks like it was a bug with Windows.

I've pushed up a fix and it seems to be working.

Would you mind trying again with the command

pnpm dlx unlighthouse@latest --site https://unlighthouse.dev

or

npx unlighthouse@latest --site unlighthouse.dev --debug

[bux]

@harlan-zw Yeah, that looks good. Thank you for the fast fix :)

Same here, I tired node 16/18/20 , npx/pnpx and nothing works

This line is failing and needs a try catch and type check around it.

I changed it like this and it works.

if (resolvedConfig.cache && typeof html !== 'object'){
    try {
       fs.writeFileSync(htmlPayloadPath, html);
    } catch (error) {
      logger.error(`Failed to write HTML payload to cache: ${error}`);
    }
  }
