The exception occurs becase an object passed to the calculatedValues array is not a valid calculated value. To solve the issue, create an instance of a CalculatedValue object.

import { CalculatedValue } from "survey-core";

survey.calculatedValues.push(new CalculatedValue({ name: "Foo", expression: "bar" }));
