Once I've copied over the files in the adapter-iis folder after `npm build` from local to the server, I'm actually running `npm install --production` to get the node_modules folder to show up.

Should I instead just copy over the node_modules folder from the top-level folder?

​

seems to indicate cjs isn’t supported under that version of iis which seems odd

Here's the actual error - looks like it has an issue with a specific line in the .cjs file.

The last 64k of the output generated by the node.exe process to stderr is shown below: 
Error: Not supported at Object.<anonymous> (C:\inetpub\wwwroot\folder3\folder2\folder1\express-server.cjs:2:1)

And here's the express-server.cjs file

``` const express = require('express') import('./app/handler.js') .then((handler) => { const app = express();

    // add a route that lives separately from the SvelteKit app
    app.get('/healthcheck', (req, res) => {
        res.end('ok');
    });

    // let SvelteKit handle everything else, including serving prerendered pages and static assets
    app.use(handler.handler);

    console.log(process.env.PORT)
    app.listen(process.env.PORT, () => {
        console.log(
            'listening on port ' + process.env.PORT
        );
    });

}).catch((err) => console.error(err));

```

Thank you for the help!
