Describe the Bug

after astro build with base config, fail loading image from script.
image path in the script should be /(base)/assets/images/image.png but it's /assets/images/image.png.
base config is ignored.

in this PR, base: astroConfig.base, was deleted, but this is NOT from viteConfig, so this line is needed
