I am using the actor in node js using apify client package. But sometimes I get this type error

TypeError: {(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)(intermediate value)} is not a function

Code:

const client = new ApifyClient({
                token: token,
            });

            if(location==null){
