How catch error message from server nodejs?

Question

Sup guys! This is the code on server side when something goes wrong:

return res.status(400).send({ error: 'Email already used!'});

And this is my frontend code that I try to catch the error message:

return async dispacth => {
        try {

            const res = await axios.post('http://localhost:3333/account/signin', userData);

            localStorage.setItem('JWT_TOKEN', res.data.token);

            dispacth({
                type: AUTH_SIGN_IN,
                token: res.data.token
            });

        } catch (err) {
            console.log(err.message)
            console.error('error', err);

            dispacth({
                type: AUTH_ERROR,
                errorMessage: err.message
            });
        }
    }

But this is what I got on browser's console:

Try err.response.body.error

Try console.log(err.response) instead of console.log(err.message).

I'm new to Node and Axios, but using "err.response" after catching "err" fixed a very similar issue I had.

For res.status(400).send('Email already used!');

You could do:

console.log(error.response.data.message);

For the error message being sent as a JSON object like res.status(400).send({ error: 'Email already used!'});

You could do:

console.log(error.response.data.error);
