Dependency resolution error thrown when using `@node-rs/argon2` with remote functions in dev

[claytercek]

Describe the bug

When importing @node-rs/argon2 in a remote function and running the project with vite dev, a dependency resolution error is thrown by Vite, and the build fails. The error does not occur during build.

This error also does not occur when importing @node-rs/argon2 in a page load() function, only in remote functions.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-argon2-remote

the index page demonstrates the behavior with remote functions, and the /loader page demonstrates the behavior when calling the same function in a page load() fn.

Logs

7:45:25 AM [vite] (client) error while updating dependencies:
Error: Error during dependency optimization:

✘ [ERROR] Could not resolve "@node-rs/argon2-wasm32-wasi"

    node_modules/@node-rs/argon2/browser.js:1:14:
      1 │ export * from '@node-rs/argon2-wasm32-wasi'
        ╵               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  You can mark the path "@node-rs/argon2-wasm32-wasi" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.

Seems like adding this to vite.config.js can help:

export default defineConfig({
  optimizeDeps: {
    exclude: ["@node-rs/argon2"],
  },

  // rest of your config ...
}
