issue with nodejs SyntaxError: Unexpected token < in JSON at position 0 [duplicate]

I got 2 files, app.js and bot.js. App.js is supposed to receive data off stripe which successfully does so and send that data to bot.js which does receive it.

Issue I’m having is SyntaxError: Unexpected token < in JSON at position 0 (can be seen on second image)

Both images are from bot.js

Here’s parts of code which sends and receives that data:

app.js

app.post('/cantshowthispart', express.json({
    type: 'application/json'
}), async (request, response) => {
    const event = request.body;

    try {
        switch (event.type) {
            case 'checkout.session.completed':
                console.log('Checkout session was successful!');
                const sessionPaymentData = event.data.object;
                if (sessionPaymentData.payment_method_types.includes('paypal')) {
                    console.log('Payment method: PayPal');
                }
                console.log(sessionPaymentData);
                
                await axios.post('http://localhost:3001/checkoutSessionCompleted', sessionPaymentData, {
                    headers: {
                        'Content-Type': 'application/json'
                    }
                });
                break;

            default:
                console.log(`Unhandled event type ${event.type}`);
        }

        response.json({ received: true });
    } catch (error) {
        console.error('Error handling the event', error);
        response.status(500).json({ error: 'Internal Server Error' });
    }
});

bot.js

app.post('/checkoutSessionCompleted', async (req, res) => {
  console.log('RECEIVED SOME DATA')

  // Handle the received data
  const reqData = req.body
  console.log(reqData)
  if (!reqData) {
    console.log('Request body is undefined!')
    return
  }


  console.log(reqData)
})

Everything else works, this part is only thing that’s bugging me.
Any help is appreciated!
