Shopify InventoryLevel response without Data

Hi everybody,

I try to receive inventory data through the Inventory Level API from Shopify.

For that, I try to get the inventory levels from multiple locations.
Unfortunately as soon as I access multiple locations, the response from the endpoint is returning 0 data or only the data from one location.
When I try to get the data from only one location its working fine:

GET /admin/api/2021-01/inventory_levels.json?location_ids=905684977

I have setup the client as described in the documentation:
https://shopify.dev/docs/admin-api/rest/reference/inventory/inventorylevel

This is the request I try to use:

GET /admin/api/2021-01/inventory_levels.json?inventory_item_ids=808950810,39072856&location_ids=905684977,487838322

 Am I doing something wrong?

Thanks in advance for your help!
