      The 4.0 transaction spec says:

      startTransaction SHOULD report an error if the driver can detect that transactions are not supported by the deployment. A deployment does not support transactions when the deployment does not support sessions, or maxWireVersion < 7, or the topology type is Sharded

      Please verify whether your MongoDB 4.0-supporting driver release raises a client side error in this case.
