Steps to reproduce

1. Install Magento2.1 from composer.
2. Add Configurable Product to the cart.
3. using paypal express checkout

Expected result

1. redirect to paypal login page

Actual result

1. PayPal gateway has rejected request. Payment has already been made for this InvoiceID (Customer Tax Group not applied on order creation #10412: Duplicate invoice)
2. 'INVNUM' => '000000001' (Paypal API request content)
3. invoice ID is always 000000001 even I manually created order in admin

Hi, @Nerogee, could you attach debug and exception log?

[Nerogee]

sorry @joni-jones , I already removed whole installation and those files are gone. I remembered at that time is when such error happened, there is no any exception. But from the debug.log I can clear see the invoice ID remain the same value.

@joni-jones, I found payment will fail with message "cant place order" when items are set with custom option. Here is the message from system.log

main.CRITICAL: Exception message: Warning: Invalid argument supplied for foreach() in /var/www/public_html/www.mydomain.com/vendor/magento/module-catalog/Model/Product.php on line 1910

as I know there are issue with custom option, it's here #5573
