Thanks all for your help.

@mega_aleksandar I tried to remove the output but same result and as @jussimannisto said it should not interfer as it is a complete normal configuration, best example is for the vendor files.

Anyway for all, I found a solution. For sure it's not the best and it should not be like that, but thanks to AI I wrote a vite plugin that fixes my css references in the manifest regarding what has been generated and it works like a charm ! I know it's not a normal solution don't have choice for now.

If anyone has a brillant idea i still take it. Cheers

Here is the vite plugin for asset fixes

START VITE PLUGIN // Plugin to fix CSS references in manifest and chunks // Best practice: Keep hashed CSS files on disk for cache busting, // but ensure manifest.json correctly references them import { Plugin } from "vite";

export function fixCssReferences(): Plugin { return { name: 'fix-css-references', enforce: 'post', generateBundle(options, bundle) { // Map to store CSS filename mappings (non-hashed -> hashed) const cssMap: Map<string, string> = new Map();

        // First pass: Build a map of CSS files with their hashes
        for (const fileName in bundle) {
            if (fileName.endsWith('.css') && fileName.includes('-')) {
                // Extract the base name without hash (e.g., "Home-b1476d91.css" -> "Home.css")
                const baseName = fileName.replace(/-[a-f0-9]{8}\.css$/, '.css');
                cssMap.set(baseName, fileName);
            }
        }

        // Second pass: Update CSS references in all chunks
        for (const fileName in bundle) {
            const chunk = bundle[fileName];

            if (chunk.type === 'chunk' && 'viteMetadata' in chunk) {
                const metadata = chunk.viteMetadata as any;

                // Update CSS imports in metadata (importedCss is a Set)
                if (metadata?.importedCss && metadata.importedCss instanceof Set) {
                    const updatedCss = new Set<string>();

                    for (const cssFile of metadata.importedCss) {
                        const hashedVersion = cssMap.get(cssFile);
                        updatedCss.add(hashedVersion || cssFile);
                    }

                    metadata.importedCss = updatedCss;
                }
            }
        }
    },
};

}
