Unexpected top-level statement "ExportDefaultExpression" in Rollup's output chunk.

Hi. When I run yarn build in my project, I get the following error:

[vite-plugin-top-level-await] Unexpected top-level statement "ExportDefaultExpression" in Rollup's output chunk. Please open an issue at https://github.com/Menci/vite-plugin-top-level-await/issues.
error during build:

It's reproducible with this commit and the following command:

git clone https://github.com/adimit/amazegen
cd amazegen
git checkout 83cabbe244
cd web/frontend
wasm-pack build --target bundler --release && yarn && yarn build

The config file looks like this:

import { defineConfig } from "vite";
import solidPlugin from "vite-plugin-solid";
import wasm from "vite-plugin-wasm";
import topLevelAwait from "vite-plugin-top-level-await";
import { nodePolyfills } from "vite-plugin-node-polyfills";

export default defineConfig({
  plugins: [wasm(), topLevelAwait(), solidPlugin(), nodePolyfills()],
  server: {
    port: 3000,
    fs: {
      allow: [".", "../../pkg"],
    },
  },
});

My node version is 16.19.0

Thank you. I'll check it.

@Menci, thank you very much. That was amazingly quick. I can confirm it worked.
