 To fix it, move the import into a different module named `*.server.js` or `*.server.ts` and import from there. In our example here, we create a new file at `utils/fs-extra.server.js`:
 
 ```js filename=app/utils/fs-extra.server.js
-export * from "fs-extra";
+export { default } from "fs-extra";
 ```
 
 And then change our import in the route to the new "wrapper" module:
 
 ```jsx filename=app/routes/index.jsx lines=[3]
 import { json } from "@remix-run/node"; // or cloudflare/deno
 
-import fs from "../utils/fs-extra.server";
+import fs from "~/utils/fs-extra.server";
 
 export async function loader() {
   return json(await fs.pathExists("../some/path"));
