How to fix 'Circular structure in "getInitialProps" result of page'?

Question

React

Good evening, when I make a request to the API, I get the error 'Circular structure in "getInitialProps" result of page'
Code:

Profile.getInitialProps = async () => {
    const res = await axios.get('http://127.0.0.1:3030/api/v1/users/1');

    console.log(res);
    return {data: res}
}

Return JSON:

{"user_id":1,"username":"asd","address":"asdaasd","status":0,"balance":"0.14067736"}

Answer 1

I decided myself, changed axios to isomorphic-unfetch, everything worked.
