cannot use scalar (variable of type uint64) as rlwe.Operand value in argument to eval.Add: uint64 does not implement rlwe.Operand (missing method isOperand)

cannot use (scaleInvariantEvaluator literal) (value of type scaleInvariantEvaluator) as circuits.EvaluatorForPolynomial value in struct literal: scaleInvariantEvaluator does not implement circuits.EvaluatorForPolynomial (wrong type for method Add)
