Lines 99 to 114 in 32e8cc1

   async load(id) { 
     if (!isVirtualTsFileFromHtml(id)) { 
       return null; 
     } 
     const htmlId = id.replace('.$au.ts', '.html'); 
     const code = await promises.readFile(htmlId, { encoding: 'utf-8' }); 
     const result = preprocess({ 
       path: htmlId, 
       contents: code, 
     }, { 
       hmrModule: 'import.meta', 
       transformHtmlImportSpecifier: s => s.replace(/\.html$/, '.$au.ts') 
     }); 
     return result!.code; 
   } 
 }; 

The preprocess in "load" func has missing options like the one in "transform" func.
I can fix it by adding missed back.

However I don't understand why we do preprocess in "load", as vite doc says "transform" is called immediately after "load". https://vitejs.dev/guide/api-plugin#universal-hooks

The "load" is definitely used by vitest.
Our normal vite+hmr is not affected by this issue.
It might affect vite build or vite wo hmr.

const htmlId = id.replace('.$au.ts', '.html');

Oh I saw the reason of load.
