Cannot read properties of undefined (reading 'imageSizes')

[deevus]

Describe the bug
When building a Next.js 15.1.6 project using next-export-optimize-images with remote-image, the build fails with the error:

TypeError: Cannot read properties of undefined (reading 'imageSizes')

To Reproduce

1. Use RemoteImage in a page
2. Run next build
3. See the error

Expected behavior
The build should succeed without the imageSizes error.
