adding salesinvoice

[eMaurits]

Hi,
I've been tryin to add a salesinvoice in the same way you are doing it in the example, only by hardcoded ID's and stuff. Did you manage to get an invoice added?

The exception i get is :
{ "error": { "code": "", "message": { "lang": "", "value": "Verplicht: Factuur voor\r\nVerplicht: Besteld door" } } }

This is the code i used. $items is an array just like the way you showed in your example.
$salesinvoice = new \Picqer\Financials\Exact\SalesInvoice($connection);

    $salesinvoide->InvoiceTo = '8578a5d2-d4cf-48f2-a299-03ab75edcc74';    
    $salesinvoice->OrderedBy = '8578a5d2-d4cf-48f2-a299-03ab75edcc74';
    $salesinvoice->YourRef = '50098';
    $salesinvoice->Description = 'Beschrijving';
    $salesinvoice->SalesInvoiceLines = $items;
    $salesinvoice->save();

I've also reached out to exact online with this error, will update if i get it working with the solution they maybe provide.
Thanks
