Image with src "${src}" is missing required "height" propert

Error message

Image with src "${src}" is missing required "height" property.

What it means

Props validation in getImgProps: without fill, the height prop is missing or undefined. Both width and height are required for statically sized images so the browser can reserve the correct aspect ratio before load.
