React Error 422 Help createError (createError.js:17)

1

Hi!
I am having trouble with my routes. the react front end keeps giving me POST http://localhost:3000/api/review/ 422 (Unprocessable Entity) when I try to submit reviews, and GET http://localhost:3000/api/review/movie/tt1825683 422 (Unprocessable Entity when I try to get reviews by imdbID.

Here’s the part of my code that is giving me issues:

API.js
createReview: review => {
        const data = {
            data: review
        }
        return axios.post('/api/review/', data);
    },

    showMovieReviews: id => {
        return axios.get('/api/review/movie/' + id);
    },

showCommentsByReview: id => {
        return axios.get('/api/comment/review/' + id);
    }

Movie.jsx

componentDidMount() {
        API.showMovieReviews(this.props.location.state.imdbID).then((reviews => {
            API.showCommentsByReview(reviews.reviewId).then(comment => console.log("Success", comment)).catch(err => console.log(err));
        })).catch(err => console.log(err));
    }

I have uploaded the rest of my code here: https://github.com/BlackMG27/cinefile-r-us. Thanks in advance.
