Could not optimize image (TypeError: Only absolute URLs are supported)

[aredean]

Hi,

I have some errors when trying to use image optimization, even I have already created process.env.
Image optimization always using my local path.

This is my plugin settings.

eleventyConfig.addPlugin(ampPlugin, {
      ampRuntimeHost:
        process.env.ENV === 'prod' ? 'https://mydomain.com' : 'http://localhost:8080',
      imageOptimization: true,
      validation: false,
    });

The error :

AMP Img Optimization WARNING Could not optimize image ({{ my local path }}\assets\{{ myfilename }}.png, 820w): TypeError: Only absolute URLs are supported

Is any wrong with the setup?

Thank you
