Message Error 'invoice creation is not allowed'

beabay

Hello!
I am creating a custom function in the shop where after the customer makes a payment, the invoice is sent immediately. I added this function in ‘Shop/onepagecontroller’.

// i took this from InvoiceController.php in the store function.
public function sendInvoice(int $orderId)
    {
        try {
            $order = $this->orderRepository->findOrFail($orderId);

            if (! $order->canInvoice()) {
                session()->flash('error', trans('admin::app.sales.invoices.create.creation-error'));
                return redirect()->back();
            }
            $items = $this->prepareInvoiceData($order);
            $request = new \Illuminate\Http\Request($items);
            
            $data = $request->validate([
                'invoice.items'   => 'required|array',
                'invoice.items.*' => 'required|numeric|min:0',
            ]);

            if (! $this->invoiceRepository->haveProductToInvoice($data)) {
                session()->flash('error', trans('admin::app.sales.invoices.create.product-error'));
                return redirect()->back();
            }

            if (! $this->invoiceRepository->isValidQuantity($data)) {
                session()->flash('error', trans('admin::app.sales.invoices.create.invalid-qty'));
                return redirect()->back();
            }
            $this->invoiceRepository->create(array_merge($data, [
                'order_id' => $orderId,
            ]));

            session()->flash('success', 'Invoice berhasil dibuat');

        } catch (\Throwable $th) {
            \Log::error('Send Invoice Error', [
                'order_id' => $orderId,
                'message'  => $th->getMessage(),
                'trace'    => $th->getTraceAsString(),
            ]);

            session()->flash('error', 'Terjadi kesalahan saat membuat invoice');
            return redirect()->back();
        }
    }

// I took this from GenerateInvoice.php
protected function prepareInvoiceData($order)
    {
        $invoiceData = ['order_id' => $order->id];

        foreach ($order->items as $item) {
            $invoiceData['invoice']['items'][$item->id] = $item->qty_to_invoice;
        }

        return $invoiceData;
    }

However, it always returns an error with the message “invoice creation is not allowed.” I hope someone can help me solve this problem.
