Error when i use mongo with the build

[4ov]

I'm trying to deploy simple api (deno - opine - mongo),
I get

error: Uncaught ReferenceError: default is not defined
const handler = mod.default;
                    ^
    at dev-server.ts:12:21

when i use mongo module from https://deno.land/x/[email protected]

Can you show me your complete code for the API endpoint?

//app.ts
import { opine } from "https://deno.land/x/[email protected]/mod.ts";
import { MongoClient } from "https://deno.land/x/[email protected]/mod.ts";

const client = new MongoClient();
client.connectWithUri("URL");
const db = client.database("NAME");
const users = db.collection<any>("COLLECTION");

const app = opine();

app.use(async (req, res) => {
  res.json(
      await users.find({ name: { $ne: null } })
    )
});



app.listen();
export default app

vercel.json
{
    "builds" : [
        {"src" : "*.ts", "use" : "[email protected]"}
    ],
    "build": {
        "env": {
            "DENO_UNSTABLE" : "true"
        }
    }
}

#bash
>vc dev
error: Uncaught ReferenceError: default is not defined
const handler = mod.default;

Thanks for that. I've distilled the issue down to a bug in deno. See denoland/deno#7649.

[TooTallNate]

This was fixed in Deno v1.4.5, which is the default version in [email protected]. Please update to this new version and let me know if you have any further issues!

There's an error says error: Uncaught PermissionDenied: access to open a plugin: /home/ma/apps/mopd/.deno_plugins/deno_mongo_f39a1ed8e4b1f4eb61e96bf8794f19af.so, run again with the --allow-plugin flag
is there any way to configure deno's flags?

[TooTallNate]

Can you try [email protected]?

[4ov]

Finally, It's working now (on dev server).
This the error i get when i try to deploy it

[TooTallNate]

Are you setting the DEBUG env var? Try unsetting that.

[4ov]

I got this too

[TooTallNate]

Looks like the mongo dependency is trying to write to the filesystem. In the serverless function environment, the filesystem is read-only, except for the /tmp directory. If possible, try to configure the module to write the necessary files to /tmp instead.

Btw the issue with using DEBUG has been resolved.
