How were you making your API call? If you’re executing from an extension (e.g. Admin Action or App Block) and using the default URL, it’s unclear exactly which API version you’ll use. It doesn’t seem to read from your .toml file OR the partner dashboard setting.
fetch("shopify:admin/api/graphql.json" ...)
you’ll need to update it to include the version number, e.g.
fetch("shopify:admin/api/2024-07/graphql.json"...)
You won’t be able to remain on 2023-10 using the old fields indefinitely.
