Issues Copying wasm files for Vercel/prod using create-t3-app

I'm trying to copy/load wasm files from a node package onnxruntime-web/dist using webpack so I can use it to inference a machine learning model I've trained. I t works locally but not on vercel. I haven't done any real web dev prior to 5 days ago. 1. Live App: https://my-t3-app-pi-three.vercel.app/ 2. Github: https://github.com/startwarfields/t3rra-viz The image is what the output is when I click the "Clicked Inference Component" on

npm run dev

npm run dev

My next.config.mjs has a webpack that tries to do this:

  webpack: (config, { isServer }) => {
    // Only perform the following steps for the client-side bundle
    if (!isServer) {
      // Copy the WebAssembly files from node_modules to the output directory
      const patterns = [
        {
          from: path.join('node_modules/onnxruntime-web/dist/*.wasm'),
          to: 'static/wasm',
        },
      ];

      config.plugins.push(new CopyWebpackPlugin({ patterns }));
    }

    return config;
  },

  webpack: (config, { isServer }) => {
    // Only perform the following steps for the client-side bundle
    if (!isServer) {
      // Copy the WebAssembly files from node_modules to the output directory
      const patterns = [
        {
          from: path.join('node_modules/onnxruntime-web/dist/*.wasm'),
          to: 'static/wasm',
        },
      ];

      config.plugins.push(new CopyWebpackPlugin({ patterns }));
    }

    return config;
  },

the full inference component is below for reference, but the line in question to load the wasm is:

    env.wasm.wasmPaths = process.env.NODE_ENV === 'production' ? 'static/wasm/' : '/';

    env.wasm.wasmPaths = process.env.NODE_ENV === 'production' ? 'static/wasm/' : '/';

import { InferenceSession, Tensor, env, } from 'onnxruntime-web';
import { useEffect } from 'react';

async function inference() {
  try {
    env.wasm.wasmPaths = process.env.NODE_ENV === 'production' ? 'static/wasm/' : '/';
    env.wasm.simd = true;
    const session = await InferenceSession.create('pipeline_xgboost.onnx');

    // prepare inputs. a tensor needs its corresponding TypedArray as data
    const input = Float32Array.from([5.5, 6.5, 4.3, 2.3]);
    const tensorA = new Tensor('float32', input, [1, 4]);

    const feeds: { [key: string]: Tensor } = { input: tensorA};


    const output  = await session.run(feeds)
    console.log(output.probabilities?.data);

  } catch (e) {
    console.error(`failed to inference ONNX model:.`, e);
  }
}
function InferenceComponent() {
  useEffect(() => {
      inference()
      .then(() => console.log('inference success'))
      .catch((error) => console.error(`failed to inference ONNX model`, error));

  }, []);

  return <div>Inference Component</div>;
}

export default InferenceComponent;

import { InferenceSession, Tensor, env, } from 'onnxruntime-web';
import { useEffect } from 'react';

async function inference() {
  try {
    env.wasm.wasmPaths = process.env.NODE_ENV === 'production' ? 'static/wasm/' : '/';
    env.wasm.simd = true;
    const session = await InferenceSession.create('pipeline_xgboost.onnx');

    // prepare inputs. a tensor needs its corresponding TypedArray as data
    const input = Float32Array.from([5.5, 6.5, 4.3, 2.3]);
    const tensorA = new Tensor('float32', input, [1, 4]);

    const feeds: { [key: string]: Tensor } = { input: tensorA};


    const output  = await session.run(feeds)
    console.log(output.probabilities?.data);

  } catch (e) {
    console.error(`failed to inference ONNX model:.`, e);
  }
}
function InferenceComponent() {
  useEffect(() => {
      inference()
      .then(() => console.log('inference success'))
      .catch((error) => console.error(`failed to inference ONNX model`, error));

  }, []);

  return <div>Inference Component</div>;
}

export default InferenceComponent;

The production error Im getting is that it's not finding the wasm files

Im finally able to continue this, ill see if the link is the solution I figured it out! It was actually a pathing issue The following code

  webpack: (config, { isServer }) => {
    // Only perform the following steps for the client-side bundle
    if (!isServer) {
      // Copy the WebAssembly files from node_modules to the output directory
      const patterns = [
        {
          from: path.join('node_modules/onnxruntime-web/dist/*.wasm'),
          to: 'static/wasm',
        },
      ];

      config.plugins.push(new CopyWebpackPlugin({ patterns }));
    }

    return config;
  },

  webpack: (config, { isServer }) => {
    // Only perform the following steps for the client-side bundle
    if (!isServer) {
      // Copy the WebAssembly files from node_modules to the output directory
      const patterns = [
        {
          from: path.join('node_modules/onnxruntime-web/dist/*.wasm'),
          to: 'static/wasm',
        },
      ];

      config.plugins.push(new CopyWebpackPlugin({ patterns }));
    }

    return config;
  },

Put the wasm assets in this directory

_next/static/wasm/onnxruntime-web/dist/

_next/static/wasm/onnxruntime-web/dist/

I checked Vercel's deployment logs to find the location of the files
