Describe the Bug

When running yarn run build in the provided reproduction repo - I receive the error - ModuleNotFoundError: Module not found: Error: Can't resolve 'mongodb' - we do not have this issue with webpack4 where we are using the following conditional

    config.plugins.push(
      new options.webpack.IgnorePlugin({
        resourceRegExp: /^pg-native$/,
      })
    );

Expected Behavior

should build and work as it does locally. I logged this in that long thread that where y'all asked for anyone having trouble migrating from 4 => 5 and it must have gotten lost in the shuffle...reason I'm logging this again is we're running in to issues with other upgraded dependencies requiring webpack5.

To Reproduce

https://github.com/followbl/webpack5-next-auth

Pull down and run yarn run build

@timneutkens this was related to the target: serverless - I follow the nextjs release docs pretty closely and didn't know this wasn't a best practice anymore. Think this is a good idea here - would recommend.
