No loader is configured for ".less" files

[lecong]

Hi,

I using x-spreadsheet in vite project and work normal with dev mode.

At production mode, i can not build success with error No loader is configured for ".less" files: ../../node_modules/x-data-spreadsheet/src/index.less

I can try resolve this issue with config:
css: {
preprocessorOptions: {
less: {
javascriptEnabled: true,
},
},
},

But cannot resolve this issue.

Call you help me resolve it?

Thanks,
