Error: Response Status: 400 at PayPal Rest SDK - node.js

Question

I created a platform with the help of NodeJS with some PayPal Payments, it all worked fine until now and I don't know why it's throwing me this error. 1 hour Ago I did a payment now it won't let me. I haven't modified any code or something like that.]
Here's the error
/Users/calinonaca/Desktop/PEDIGREE-NOTES copy/controllers/feed.js:863
throw error;
^
Error: Response Status : 400

at process._tickCallback (internal/process/next_tick.js:63:19)
And here's my function
exports.postPayment = (req,res,next) => {
const uploadedBy = req.body.noteOwner;
const finalprice = req.body.finalprice;
const notename = req.body.notename;
const loggedInUser = req.session.user._id;
const noteprice = req.body.noteprice;
const create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://localhost/successPayment/"+finalprice+"/"+notename+"/"+uploadedBy+"/"+noteprice+"/"+loggedInUser,
"cancel_url": "http://localhost/cancel"
},
"transactions": [{
"item_list": {
"items": [{
"name": "Note",
"sku": "001",
"price": finalprice,
"currency": "USD",
"quantity": 1
}]
},
"amount": {
"currency": "USD",
"total": finalprice
},
"description": "Note you ordered"
}]
};
paypal.payment.create(create_payment_json, function (error, payment) {
if (error) {
throw error;
} else {
for(let i = 0; i < payment.links.length; i++)
{
if(payment.links[i].rel === 'approval_url')
{
res.redirect(payment.links[i].href);
}
}
}
});
}
It all worked fine until now and I don't know what is wrong, can you please help me? Thank you!

i hope this will help, i had the same problem and i had to dig almost all possible links and resources, what i found is that you have to map EXACTLY SAME OBJECT AS HERE
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"transactions": [
{
"amount": {
"total": "30.11",
"currency": "USD",
"details": {
"subtotal": "30.00",
"tax": "0.07",
"shipping": "0.03",
"handling_fee": "1.00",
"shipping_discount": "-1.00",
"insurance": "0.01"
}
},
"description": "The payment transaction description.",
"custom": "EBAY_EMS_90048630024435",
"invoice_number": "48787589673",

},

},
{

"description": "Black handbag.",
"quantity": "1",
"price": "15",
"tax": "0.02",
"sku": "product34",
"currency": "USD"
}
],
"shipping_address": {
"recipient_name": "Brian Robinson",

"city": "San Jose",
"country_code": "US",
"postal_code": "95131",
"phone": "011862212345678",

}
}
}
],
"note_to_payer": "Contact us for any questions on your order.",
"redirect_urls": {
"return_url": "https://example.com/return",
"cancel_url": "https://example.com/cancel"
}
Only after i copied and pasted this object i got a successful response with redirect urls. I hope this will help you. I will play around with object to see if there is anything to neglect.
