Hi @RB10100,
If, for example, you send a request to the endpoint http://your.domain.com/rest/V1/orders/1 (I'm assuming you have an order with the internal id 1), what it would be the result?
My array has, at some point, somenthing like this:
)
[status_histories] => Array
(
)
[extension_attributes] => stdClass Object
(
[shipping_assignments] => Array
(
[0] => stdClass Object
(
[shipping] => stdClass Object
(
[address] => stdClass Object
(
[address_type] => shipping
