Paypal Api Do not pass PAY-XXX or PAYID-XXX directly

Everything in my system was in good condition, but since yesterday I get an error like this I could not understand why?

Error: Do not pass PAY-XXX or PAYID-XXX directly into createOrder. Pass the EC-XXX token instead

This is my Smart Payment Button script

<script>
  paypal.Buttons({
        style: {
          layout: 'vertical',
          color: 'black',
          shape: 'rect',
          label: 'paypal',
          tagline: false,
          size: 'responsive',
        },

        createOrder: function() {

          var SETEC_URL = '/api/create-payment';
          var checkBox = document.getElementById("ship_to_different");
          var note = $("#ordernote").val();
          if (checkBox.checked == true) {
            var body = $("#checkoutt, #data").serializeArray();
          } else {
            $('input[name=note]').val(note);
            var body = $("#data").serializeArray();

          }
          $("#wait").show();
          return fetch(SETEC_URL, {

This is my backend Create-Payment function:

public function createorder(Request $request){

    }

        }
    }


    if(isset($coupon)){

        $subtotalpay = $coupon;

    }

    if($taxpay == '1'){
        $tax = round($subtotalpay * 8.625/100,2);

    }else{
        $tax = 0;
    }
    $itemList = new ItemList();
    $itemList->setItems($items);


    $details = new Details();
    $details->setShipping($shippingpay)

    }

    $approvalUrl = $payment->getApprovalLink();

And this is Execute-Payment function

public function execute(Request $request){

    $execution = new PaymentExecution();
    $execution->setPayerId($request->payerID);

    try{
        $result = $payment->execute($execution, $apiContext);
        $res = $result->transactions[0]->related_resources[0]->sale->id;
        $res2 = $result->transactions[0]->invoice_number;
        $res3 = $result->getId();

        Transactions::create([
            'ip' => Request::ip(),
            'transaction_id' => $res,
            'invoice_id' => $res2,
            'payment_id' => $res3
        ]);
        Refunds::create([

            'transaction_id' => $res,
            'invoice_id' => $res2,
            'payment_id' => $res3,
            'amount' => '0'
        ]);

    }catch (Exception $e){
        echo $e->getMessage();
        exit(1);
    }


}

public function validateorder(Request $request)
{
    if($request['status']) {
        $messages = array(

        );
        $validator = Validator::make($request->all(), [

    }elseif($request['guest']) {

        ]);
    }elseif($request['x1']) {
        $validator = Validator::make($request->all(), [
            'email' => 'required'

        ]);
    }
        try

            if ($validator->fails()) {

            }
        }
        catch (Exception $e){
        }

    }

What is wrong?
