fix(next/image): improve warning when `fill` and `sizes="100vw"` #61949

styfle · 2024-02-12T16:20:53Z

Previously, this error was confusing because it made it sound like the sizes prop was missing. This was because the default value of sizes is 100vw so the previous code couldn't tell the different between implicit vs explicit 100vw.

This PR changes the code to read the input value from the sizes prop and prints a better warning.

Fixes NEXT-2441

Fixes #58586
