PLEASE Give Me Advice For new GraphQL-inventoryTransfers Scope Issues

I am currently trying to get past inventory transfer history using the new “inventoryTransfers” scope from the unstable version of GraphQL on Shopify. The response is returned successfully, but the data is returned empty. I will attach the code below, so I would appreciate any advice on where the mistake is.

import requests, json
import pandas as pd

shop_creds = "shop_creds.json"
with open(shop_creds) as f:
    shop_creds = json.load(f)

api_version = 'unstable'
domain = f'https://{shop_creds["shop_name"]}.myshopify.com'
endpoint = f'/admin/api/{api_version}/graphql.json'
url = domain + endpoint

headers = {
    'Content-Type': 'application/json',
    'X-Shopify-Access-Token': shop_creds['api_token']
}

query = """
query($after: String, $query: String) {
  inventoryTransfers(first: 20, query: $query, reverse: false, after: $after) {
    edges {
      node {
        dateCreated
        destination{
          address1
          address2

        }
        origin{
          address1

          name
        }
        lineItems(first: 50) {

I’m using Jupiter notebook, Python version: 3.12.0
and, credentials is written in shop_creds.json file.

The old inventory transfers are not available via the API. This is for new inventory transfers

thank you for replying!
yes, i’m trying to use new version, inventoryTansfers scope.
the reason i set “2024-11-01” as start-date is just i want to get the inventory transfer data from 2024-11-01.

Have you created inventory transfers via the new API?
Existing Inventory Transfers visible in Shopify Admin or Stocky won’t be available through this API.

Ah, i have to create new inventory transfers via this new API?
so, you mean i can’t get the past inventory transfer data via this new API?

No you can’t get past ones via this API at the moment. It is unstable so behaviour might change.

i see.
just for now, i can’t.
OK!! Thank you for letting me know it.
I’ll wait for the new version release.
