In fact, I don't know but Could try this? I've changed user_fields line.
Also, check out developers.google.com/+/web/api/re...

knpu_oauth2_client:
    clients:
        google:
            # must be "google" - it activates that type!
            type: google
            # add and configure client_id and client_secret in parameters.yml
            client_id: '%env(resolve:GOOGLE_CLIENT_ID)%'
            client_secret: '%env(resolve:GOOGLE_CLIENT_SECRET)%'
            # a route name you'll create
            redirect_route: connect_google_check
            redirect_params: {}
            # Optional value for sending access_type parameter. More detail: https://developers.google.com/identity/protocols/OpenIDConnect#authenticationuriparameters
            # access_type: ''
            # Optional value for sending hd parameter. More detail: https://developers.google.com/identity/protocols/OpenIDConnect#hd-param
            # hosted_domain: ''
            # Optional value for additional fields to be requested from the user profile. If set, these values will be included with the defaults. More details: https://developers.google.com/+/web/api/rest/latest/people
            user_fields: {'birthday'}
            # whether to check OAuth2 "state": defaults to true
            # use_state: true
