Hi @tkdgy_dl ,

You should try mongodb-atlas instead.

If that doesn’t work can you go into function UI and copy paste the URL in the browser here

Thanks

I find the answer your problem.
In Atlas UI > Triggers, you have to press “Link” button after choice your Link Data Source(s).

The reason for the error in TypeError is not connected “Link Data Source(s)”, so occur ‘db’ of undefined.
