I am trying to submit a form to my local database but I keep receiving an error message:

> 
> :Error: Objects are not valid as a React child (found: Error: Network Error). If you meant to render a collection of children, use an array instead
> 
>

Could anyone give me some insight on what's going on and how I could fix it? Here's the code:

```js
import axios from 'axios';
import type  { FC } from 'react';
import { useState } from 'react';
import { useForm, SubmitHandler } from 'react-hook-form';
import './AgentForm.css';

interface IFormInputs {
    firstName: string;
    lastName: string;
    photoUrl: string | null; 
    agentLicence: string; 
    address: string; 
    practiceAreas: string;
    aboutMe: string | null;
}

const AgentForm: FC = () => {
    const { register, handleSubmit, formState: {errors} } = useForm<IFormInputs>();
    const [error, setError] = useState<string>("");
    const [eventCreated, setEventCreated] = useState<boolean>(false);

    const submitForm: SubmitHandler<IFormInputs> = async (agent: IFormInputs) => {
        if (!agent.photoUrl) {
            agent.photoUrl = null;
        }
        if (!agent.aboutMe) {
            agent.aboutMe = null;
        }
        // console.log(JSON.stringify(agent))

        try {
            await axios.post('http://localhost:3001/agents', JSON.stringify({
                firstName: agent.firstName,
                lastName: agent.lastName,
                photoUrl: agent.photoUrl,
                agentLicence: agent.agentLicence, 
                address: agent.address, 
                practiceAreas: agent.practiceAreas,
                aboutMe: agent.aboutMe
            }));
            setEventCreated(true);
            setError('');
        } catch (error) {
            setError(error);
        }  
    }

  return (
    <>
