@btspoony could you please share your vite setup?
I can't reproduce it with the standard templates

[btspoony]

I am using astro.build and typescript
simple vite config in astro.config.mjs

export default defineConfig({
  output: "server",
  vite: {
      assetsInclude: ["**/*.cdc"],
      ssr: {
        external: [
          "@onflow/fcl",
          "@onflow/fcl-wc",
        ],
      },
    }
}

The original version can run normally in astro dev, but it will throw an error during astro build.
After the modification, both dev mode and build can run normally.
