Airtable not recognising process.env.AIRTABLE_API_KEY

Hello all, I am a learning developer so hopefully my code is not too confusing.
I want to create a form in React that feeds data onto Airtable. Using the Airtable SDK I am able to do it when I insert the API key into the code.

const base = new Airtable({ apiKey: API_KEY }).base(
    "base-name"
)

However, if I use process.env.AIRTABLE_API_KEY it gives an error saying: Uncaught Error: An API key is required to connect to Airtable.

import { useState } from 'react';
require('dotenv').config()



const Airtable = require('airtable');


const base = new Airtable({ apiKey: process.env.AIRTABLE_API_KEY }).base(
    "base-name"
)

const table = base("table-name")


const Form = () => {
    const [firstNameInput, setFirstNameInput] = useState('');
    const [lastNameInput, setLastNameInput] = useState('');
    const [emailInput, setEmailInput] = useState('');
    const [interestInput, setInterestInput] = useState('');
    const [phoneInput, setPhoneInput] = useState('');


    const resetForm = () => {
        setFirstNameInput('');
        setLastNameInput('');
        setEmailInput('');
        setInterestInput('');
        setPhoneInput('');
    }

    const createData = async () => {
        try {
            const createdRecord = await table.create([
                {
                    fields: {
                        firstName: firstNameInput,
                        lastName: lastNameInput,
                        email: emailInput,
                        interest: interestInput,
                        phone: phoneInput
                    }
                },
            ])
            return createdRecord
        } catch (err) {
            console.error(err)
        }
    }

    const handleSubmit = async (e) => {
        e.preventDefault()
        try {
            await fetch(createData(), {
                method: "POST",
                body: JSON.stringify({
                    firstName: firstNameInput,
                    lastName: lastNameInput,
                    email: emailInput,
                    interest: interestInput,
                    phone: phoneInput,
                }),
            })
            resetForm()
        } catch (err) {
            console.error(err)
        }
    }

    return (
        <div className='section section-center'>
            <form onSubmit={handleSubmit}>

                </button>
            </form>
        </div>
    )
}

export default Form

When using process.env.AIRTABLE_API_KEY in a different component that only fecthes data using axios, it is able to to read.
Any help would be greatly appreciated. Thank you!

I’ve tried using another solution for the form I found here on the forums, using axios and setting the headers. Unfortunately the same problem occurs where I have to set the key in text and cannot use an environment variable. I am very confused as the same application is able to read the variable when fetching data but cannot create data…

Here is what I tried:

const Form = () => {
    const [firstNameInput, setFirstNameInput] = useState('');
    const [lastNameInput, setLastNameInput] = useState('');
    const [emailInput, setEmailInput] = useState('');
    const [interestInput, setInterestInput] = useState('');
    const [phoneInput, setPhoneInput] = useState('');

    const data = {
        "fields": {
            "firstName": firstNameInput,
            "lastName": lastNameInput,
            "email": emailInput,
            "interest": interestInput,
            "phone": phoneInput
        }
    }

    const resetForm = () => {
        setFirstNameInput('');
        setLastNameInput('');
        setEmailInput('');
        setInterestInput('');
        setPhoneInput('');
    }


    let url = 'https://api.airtable.com/v0/table-id/table-name'

    let axiosConfig = {
        headers: {
            'Authorization': `Bearer ${process.env.AIRTABLE_API_KEY}`,
            'Content-Type': 'application/json'
        }
    }

    const handleSubmit = async (e) => {
        e.preventDefault()
        axios
            .post(
                url,
                data,
            axiosConfig
            )
            .then(resp => console.log(resp))
            .catch(error => console.log(error))
            resetForm()
    }

EDIT: Nevermind, this approach works!

I am trying a different approach now. Using a serverless function:

require('dotenv').config()
const Airtable = require('airtable-node')

const airtable = new Airtable({
        apiKey: process.env.AIRTABLE_API_KEY
    })
    .base('baseID')
    .table('sometablename')

exports.handler = async (event, context, cb) => {
    const method = event.httpMethod
    if (method !== 'POST') {
        return {
            statusCode: 405,
            body: 'Only POST Requests Allowed',
        }
    }
    const {
        fields
    } = JSON.parse(event.body)
    console.log(fields);
    try {
        const item = await airtable.create(
            {fields}
        )
        console.log(item)
        if (item.error) {
            return {
              statusCode: 400,
              body: JSON.stringify(item),
            }
          }
        return {
            headers: {
                Authorization: "Bearer " + process.env.AIRTABLE_API_KEY,
                'Content-Type': 'application/json'
            },
            statusCode: 201,
            body: 'Success',
        }

    } catch (error) {
        return {
            statusCode: 400,
            body: 'Server Error',
        }
    }
}

This is the code of the Component:

   async function handleSubmit(e) {
        e.preventDefault()
        const
            fields = {
                firstName : firstNameInput,
                lastName : lastNameInput,
                email : emailInput,
                interest : interestInput,
                phone : phoneInput
            }
        try {
            await axios.post(`/api/posting`, {
                fields
            },)

            resetForm();
            return fields
        } catch (error) {
            console.log(error.response)
            return null
        }
    }

And this is the error I get:

{
  firstName: 'ReallyLongNameToStandOut',
  lastName: 'Last Try',
  email: 'asas@ee.com',
  interest: 'Other',
  phone: '1234'
}
{
  error: { type: 'INVALID_PERMISSIONS', message: 'Invalid permissions' }
}

Any ideas on what I should do?
