API help required

As per this documentation ( http://docs.devapiverson.apiary.io/ )

I did but when I try to get orders:
Endpoint: /order/?status=awaiting_fulfillment

When trying to filter order on the basis of status “awaiting_fulfillment”

I encounter this error
{
“error_message”: “expected one of [‘all’, ‘archived’, ‘cancelled’, ‘in_process’, ‘new’, ‘shipped’]”,
“param”: “status”
}

All this status supported by this API ( https://ordoro.docs.apiary.io/ )
