vite.config.ts does not work

[deleonio]

If I provide my own configuration, the build no longer works.

// windi.config.ts
import vue from '@vitejs/plugin-vue';

export default {
  plugins: [
    vue({
      template: {
        compilerOptions: {
          isCustomElement: (tag) => {
            console.log('isCustomElement', tag);
            return tag === 'kol-counter';
          },
        },
      },
    }),
  ],
};

How can I extend the configuration without errors?

I will check this later...

Vue plugin is controlled by Slidev, use this instead:
