Question

Hello

I was going through the issues section to find out an solution for the issue i am facing.. I did tried some of the solutions provided by xenova but it seems like I am getting some wasm fallback error which I have no idea whats happening.. I doubt its on webpack but I wanted a clarity.

The error I see is like this while running npm run dev

Something went wrong during model construction (most likely a missing operation). Using `wasm` as a fallback.

export default nextConfig;

Any help is appreciated. Thanks.
