Error while consuming the custom search engine google api

I have a ReactJs app with a search bar and i want to consume the API custom search engine of google and im having the following error:

"Request contains an invalid argument."

The docs of the API shows the following url:

https://customsearch.googleapis.com/customsearch/v1?key=[YOUR_API_KEY]

Im using the exact url but instead i paste my API_KEY without the brackets.

This is my reactjs component
Search.js:

import axios from 'axios'
import Searchbar from '../molecules/Searchbar'
import { useState } from 'react';


const Search = () => {    
  
  const [searchText, setSearchText] = useState('');
  
  function searchInGoogle(e){
    
    const BASE_URL = `https://customsearch.googleapis.com/customsearch/v1`
    const API_KEY = process.env.REACT_APP_SEARCH_KEY;
    const SEARCH_ENGINE_KEY = process.env.REACT_APP_SEARCH_ENGINE_KEY;
    var apiCall = `${BASE_URL}?key=${API_KEY}&q=${searchText}`
    axios.get(apiCall).then(function (response){
      console.log(response)
    }).catch(function(error){
      console.log(error);
    })
    
  }

  const handleInputChange = (e) => {
    setSearchText(e.target.value)
  }
  
  console.log(searchText)

  return (
    <div>
      <input className='searchInput' onChange={handleInputChange} ></input>
      <button className='btn' onClick={searchInGoogle} >Submit</button>
      {/* <Searchbar /> */}
    </div>
  )
}

export default Search
I tried both ways:

`${BASE_URL}?key=${API_KEY}&cx=${SEARCH_ENGINE_KEY}&q=${searchTerm}`

and

`${BASE_URL}?key=${API_KEY}&q=${searchTerm}`

In my console i get GEThttps://customsearch.googleapis.com/customsearch/v1?key=undefined&q=asd

>Solution :

In a project created by create-react-app, only env vars beginning with REACT_APP_ are defined in process.env.

Change your .env file to include

REACT_APP_SEARCH_KEY=xxxxx
REACT_APP_SEARCH_ENGINE_KEY=xxxxx

You should also use Axios’ params config to correctly and safely encode query parameters. Eg

// search.js
import axios from "axios";

const BASE_URL = "https://customsearch.googleapis.com/customsearch/v1";
const API_KEY = process.env.REACT_APP_SEARCH_KEY;
const SEARCH_ENGINE_KEY = process.env.REACT_APP_SEARCH_ENGINE_KEY;

export const searchInGoogle = async (searchTerm) => {
  // don't forget `await`
  const { data } = await axios.get(BASE_URL, {
    params: {
      key: API_KEY,
      cx: SEARCH_ENGINE_KEY,
      q: searchTerm,
    },
  });
  return data;
};

import { useState } from "react";
import { searchInGoogle } from "./search";

const Search = () => {
  const [searchText, setSearchText] = useState("");

  const handleSubmit = (e) => {
    e.preventDefault();

    searchInGoogle(searchText).then(console.log).catch(console.error);
  };

  const handleInputChange = (e) => {
    setSearchText(e.target.value);
  };

  return (
    <div>
      <input className="searchInput" onChange={handleInputChange}></input>
      <button className="btn" onClick={searchInGoogle}>
        Submit
      </button>
    </div>
  );
};
