( session: options?.session, ^ SyntaxError: Unexpected token '.')mongoose give a error deploying in instance ubuntu aws

Question

I have this error while using mongoose:

/var/www/node-api/node_modules/mongoose/node_modules/mongodb/lib/admin.js:62
            session: options?.session,
                             ^

SyntaxError: Unexpected token '.'

I reinstalled node_modules but I always get the same problem.

For mongoose and my connection in my device it worked correctly.

Adding an answer for this because it keeps coming up.

Problem:

Mongoose uses the MongoDB native Node.js driver as one of it's dependencies.

In the mongodb V6 native driver they implemented optional chaining in the async command() within admin.js:

async command(command, options) {
   return (0, execute_operation_1.executeOperation)(this.s.db.client, new run_command_1.RunAdminCommandOperation(command, {
      ...(0, bson_1.resolveBSONOptions)(options),
      session: options?.session, //< optional chaining here
      readPreference: options?.readPreference
   }));
}

The problem is that optional chaining wasn't supported in Node.js until V14.5.

Solution:

You need to upgrade your Node.js version to a newer version. At the current time of writing, Node V20 is the LTS so I would recommend upgrading to that or see the Release Schedule to plan ahead.
