Rest API: Register and Login errors aren’t specific

The problem I was having is that I wasn’t receiving the full error object. To do that I changed the code to:

    const { username, password, email } = this.state;
    axios
      .post(`${Config.apiUrl}/wp/v2/users/register`, {
        username: username,
        password: password,
        email: email,
      })
      .catch(err => {
        console.log({err})
      });

Which then allowed me to figure out that the error message is contained in:
err.response.data.message

So now I’m all good.
