I'm using REST API with token authentication to export data from a M1 to a fresh installation of M2.2.0 installation.
Everything works fine with customers and products, but I cannot manage to understand how to create an order without creating a cart.
I mean, I already have all needed data from the order, there should be no need to create a cart before, as suggested in all the solutions I found (also in the official magento guide).
I'm following same steps in the above mentioned guide, but trying to post data about the order, I keep getting the error:
"Fatal Error: 'Uncaught Error: Call to a member function getMethodInstance() on null in \/var\/www\/html\/app\/code\/Magento\/Payment\/Observer\/SalesOrderBeforeSaveObserver.php:24\nStack trace:\n#0 \/var\/www\/html\/lib\/internal\/Magento\/Framework\/Event\/Invoker\/InvokerDefault.php(72): Magento\\Payment\\Observer\\SalesOrderBeforeSaveObserver->execute(Object(Magento\\Framework\\Event\\Observer))\n#1 \/var\/www\/html\/lib\/internal\/Magento\/Framework\/Event\/Invoker\/InvokerDefault.php(60): Magento\\Framework\\Event\\Invoker\\InvokerDefault->_callObserverMethod(Object(Magento\\Payment\\Observer\\SalesOrderBeforeSaveObserver), Object(Magento\\Framework\\Event\\Observer))\n#2 \/var\/www\/html\/lib\/internal\/Magento\/Framework\/Event\/Manager.php(66): Magento\\Framework\\Event\\Invoker\\InvokerDefault->dispatch(Array, Object(Magento\\Framework\\Event\\Observer))\n#3 \/var\/www\/html\/generated\/code\/Magento\/Framework\/Event\/Manager\/Proxy.php(95): Magento\\Framework\\Event\\Manager->dispatch('sales_order_sav...', Array)\n#4 \/var\/www\/html\/lib\/internal\/Magento\/Framework\/Model\/AbstractModel.php(694):' in '\/var\/www\/html\/app\/code\/Magento\/Payment\/Observer\/SalesOrderBeforeSaveObserver.php' on line 24"
and this is a sample JSON I'm using to make my tries:

EDIT
Using the json in this question I managed to create the order.
