title: 'next/image Un-configured qualities'

Why This Error Occurred

One of your pages that leverages the next/image component, passed a quality value that isn't defined in the images.qualities property in next.config.js.

Possible Ways to Fix It

Add an entry to images.qualities array in next.config.js with the expected value. For example:

module.exports = {
  images: {
    qualities: [25, 50, 75],
  },
}
