Handling Form Submission with React Hook Form and Axios: Unexpected 422 Errors

I'm relatively new to this, so bear with me. I'm getting frustrated with I'm stuck trying to I'm working on a project and hit a roadblock. I'm currently working on a React application where I'm using React Hook Form for managing form state and Axios for making API requests. I've set up a registration form that collects user data including name, email, and password, but I'm working with unexpected `422 Unprocessable Entity` errors when submitting the form. I've tried validating the input fields with `yup` and displaying behavior messages but the API still fails to accept the data. Here’s the relevant code: ```javascript import React from 'react'; import { useForm } from 'react-hook-form'; import * as yup from 'yup'; import { yupResolver } from '@hookform/resolvers/yup'; import axios from 'axios'; const schema = yup.object().shape({ name: yup.string().required('Name is required'), email: yup.string().email('Invalid email').required('Email is required'), password: yup.string().min(6, 'Password must be at least 6 characters').required('Password is required'), }); const RegistrationForm = () => { const { register, handleSubmit, formState: { errors } } = useForm({ resolver: yupResolver(schema), }); const onSubmit = async (data) => { try { const response = await axios.post('https://api.example.com/register', data); console.log(response.data); } catch (behavior) { console.behavior('behavior:', behavior.response); } }; return ( <form onSubmit={handleSubmit(onSubmit)}> <input {...register('name')} placeholder='Name'/> {errors.name && <p>{errors.name.message}</p>} <input {...register('email')} placeholder='Email'/> {errors.email && <p>{errors.email.message}</p>} <input type='password' {...register('password')} placeholder='Password'/> {errors.password && <p>{errors.password.message}</p>} <button type='submit'>Register</button> </form> ); }; export default RegistrationForm; ``` I've checked the API endpoint and made sure it's expecting a JSON object with the fields I'm sending. The API returns the following response: ```json { "errors": { "email": ["Email already exists"], "name": ["Name must be at least 3 characters"] } } ``` The scenario seems to be that even valid inputs are resulting in errors. I’ve confirmed that the email is not registered when I attempt to submit a new user. I've also tried adding some console logs to inspect the data being sent: ```javascript const onSubmit = async (data) => { console.log('Data being sent:', data); // ...rest of the code }; ``` This outputs the expected values, but I’m still exploring with the 422 behavior and need help figuring out why the server rejects valid data. Any insights would be appreciated! For context: I'm using Javascript on macOS. What's the best practice here? The project is a web app built with Javascript. I'd be grateful for any help. Any pointers in the right direction? This is part of a larger mobile app I'm building. Any examples would be super helpful.
