Unable to create fulfillment service

[mlundqvi]

Hi, 

I am trying to create a new fulfillment service for an existing location using admin/api/2024-01/fulfillment_services.json REST end-point. 

The request body I use is: 

{
  "fulfillment_service": {
    "name": "<Name>",
    "admin_graphql_api_id":"gid://shopify/FulfillmentService/1",
    "inventory_management": false,
    "permits_sku_sharing": false,
    "fulfillment_orders_opt_in": false,
    "tracking_support": false,
    "format": "json",
    "location_id": "<Id>"
  }
}

I get no errors, but the response body simply says:

{
"fulfillment_services": []
}

Any advice?

Thank you
