I'm trying to store an order for later transaction submissions.  I package the items as listed in the sdk and I can see they are properly added to the object.  However when I submit the createOrder I get this error:

"errors":[{"category":"INVALID_REQUEST_ERROR","code":"VALUE_EMPTY","detail":"Field must not be blank","field":"line_items[0].quantity"}
 

There is a quantity associated with the line item in the object so I don't understand what is the error.

I tried to package the line items in an array and inside [] but that didn't help.

Here's the object that I submit in the createOrders as the "body":

array(2) { [0]=> object(SquareConnect\Model\CreateOrderRequestLineItem)#13 (15) { ["name":protected]=> NULL ["quantity":protected]=> NULL ["base_price_money":protected]=> NULL ["variation_name":protected]=> NULL ["note":protected]=> NULL ["catalog_object_id":protected]=> NULL ["modifiers":protected]=> NULL ["taxes":protected]=> NULL ["discounts":protected]=> NULL ["setName"]=> string(23) "rfOrg Test Subscription" ["setQuantity"]=> string(1) "2" ["setBasePriceMoney"]=> object(SquareConnect\Model\Money)#16 (4) { ["amount":protected]=> NULL ["currency":protected]=> NULL ["setAmount"]=> int(100) ["setCurrency"]=> string(3) "USD" } ["setVariationName"]=> string(6) "normal" ["setNote"]=> string(3) "boo" ["setCatalogObjectId"]=> string(0) "" } [1]=> object(SquareConnect\Model\CreateOrderRequestLineItem)#17 (15) { ["name":protected]=> NULL ["quantity":protected]=> NULL ["base_price_money":protected]=> NULL ["variation_name":protected]=> NULL ["note":protected]=> NULL ["catalog_object_id":protected]=> NULL ["modifiers":protected]=> NULL ["taxes":protected]=> NULL ["discounts":protected]=> NULL ["setName"]=> string(18) "Paleo Subscription" ["setQuantity"]=> string(1) "1" ["setBasePriceMoney"]=> object(SquareConnect\Model\Money)#19 (4) { ["amount":protected]=> NULL ["currency":protected]=> NULL ["setAmount"]=> int(100) ["setCurrency"]=> string(3) "USD" } ["setVariationName"]=> string(6) "normal" ["setNote"]=> string(3) "boo" ["setCatalogObjectId"]=> string(0) "" } }
 

any help is appreciated.   

thanks
