All Orders of the previous financial year are not coming using Shopify Orders API

I want to fetch all orders from the previous financial year to the current date using the Shopify orders API.
I use these query parameters in this API call.
Array
(
[order] => id
[created_at_min] => 2020-04-01T00:00:00-00:00
[created_at_max] => 2021-07-22T00:00:00-00:00
[status] => any
[last_id] => 3859112034413
[limit] => 250
[direction] => next
)

API End Point: admin/api/2021-07/orders.json and my query parameters.

Total numbers of orders = 9387.
But, I have only got 1798 orders data. The response of the 9th iteration is empty.

Can someone please tell me how to get all order data and what will be the query parameters?
