import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';

and

const notify = () => toast("Wow so easy!");

and

<button onClick={notify}>Notify!</button>

    try {
        const response = await fetch('/generate_pdf', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
            },
        });
        const responseData = await response.json();
        const pdfURL = responseData.pdf_url;
        localStorage.setItem("pdf_url", pdfURL)
        // window.open(pdfURL, '_blank');
        if (!response.ok) {
            throw new Error('Network response was not ok');
        }
    }
    catch (error) {
        console.error('Error fetching data:', error);
    } 
};

You just need to call the toast function wherever you need it.

import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';

const notify = () => toast("Wow so easy!");

async function toBeCalledByEventListener() {
   ...
     // if the response was successful call the notification function
     const responseData = await response.json();
     const pdfURL = responseData.pdf_url;
     localStorage.setItem("pdf_url", pdfURL)
     // window.open(pdfURL, '_blank');
     notify()
     if (!response.ok) {
       toast("An unexpected error occurred, please try again later.")
       throw new Error('Network response was not ok');
     }


   ...
}

I guess you want to toast where you console. try the code below:

async function toBeCalledByEventListener() {
    try {
        const response = await fetch('/generate_pdf', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
            },
        });
        const responseData = await response.json();
        const pdfURL = responseData.pdf_url;
        localStorage.setItem("pdf_url", pdfURL)
        // window.open(pdfURL, '_blank');
        if (!response.ok) {
            throw new Error('Network response was not ok');
        }
    }
    catch (error) {
        toast(error) // where i add some code
        console.error('Error fetching data:', error);
    } 
}

Because the function named notify cannot pass any params, just use the function toast instead.

it is the function changes

async function toBeCalledByEventListener() {
      try {
        const response = await fetch('/generate_pdf', {
          method: 'POST',
          headers: {
            'Content-Type': 'application/json',
          },
        });
    
        const responseData = await response.json();
        const pdfURL = responseData.pdf_url;
        localStorage.setItem("pdf_url", pdfURL);
    
        // Display a success toast
        toast.success("PDF generated successfully!");
    
        // window.open(pdfURL, '_blank');
    
        if (!response.ok) {
          throw new Error('Network response was not ok');
        }
      } catch (error) {
        // Display an error toast
        toast.error('Error generating PDF:', error.message);
      }
    }

your app.js changes :

function App() {
  // ... other components

  return (
    <div>
      {/* ... other content */}
      <ToastContainer /> {/* Add this line */}
    </div>
  );
}

Here I have modified your code and make it easy to use.

Make sure you have react-toastify installed. You can install it using npm
https://www.npmjs.com/package/react-toastify

Import the necessary components and styles from react-toastify at the top of your file.

// Import required dependency 
import React, { useEffect } from 'react'
import { ToastContainer, toast } from 'react-toastify';
import 'react-toastify/dist/ReactToastify.css';

const ErrorHandling = () => {
    
    // Create a function that will be responsible for showing the error notification. In your case, it's the notify function.
    const notify = (msg) => toast.error(msg);

    async function toBeCalledByEventListener() {
        try {
          const response = await fetch('/generate_pdf', {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json',
            },
          });
      
          const responseData = await response.json();
          const pdfURL = responseData.pdf_url;
          localStorage.setItem('pdf_url', pdfURL);
      
          if (!response.ok) {
            throw new Error('Network response was not ok');
          }
      
        } catch (error) {
          console.error('Error fetching data:', error);

        //   Update your error handling logic to use the notify function whenever an error occurs.
        notify('Network response was not ok');
        }
      }
      

      useEffect(()=>{
        toBeCalledByEventListener();
      },[])

  return (
    // Finally, render the ToastContainer component at the root level of your component.
    <>
     <ToastContainer  />
    </>
  )
}

export default ErrorHandling

This will resolve your problem.
