App works fine on Local but when deployed. I'm getting Error: In the module 'bson' on reder.com, a SyntaxError is displayed: Unexpected token '?='

The nullish coalescing assignment operator from your logs - ??= - requires a newer version of Node than the current Render default.

The deploy logs show the Node version being used and a link to the docs on how to change it, e.g.

==> Using Node version 14.17.0 (default)
==> Docs on specifying a Node version: https://render.com/docs/node-version

Specify a Node version to match the one you developed/tested with.
