How to solve CORS error when fetching local wasm file in javascript

Question

I am new with WebAssembly and I am trying with a sample Go WebAssembly project. After compiling into main.wasm, I am trying to fetching main.wasm using the following javascript code:

  async function init() {
    const go = new Go();
    const filePath = './wasm/main.wasm';
    const response = await fetch(filePath);
    const buffer = await response.arrayBuffer();
    const result = await WebAssembly.instantiate(
      buffer,
      go.importObject
    );
    go.run(result.instance);
  }

  init();

All I get is an error about CORS policy:

Access to fetch at 'file:///......../wasm/main.wasm' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https, isolated-app.

How can I bypass CORS policy when fetching local file in this case? Thank you in advanced.
