Contracts query returning empty

[ThiagoMine]

I'm developing an app that will do subscriptions using the post-purchase extension, as documented at https://shopify.dev/apps/checkout/post-purchase/add-subscription-post-purchase-app-extension.

I've already developed the extension itself and generated some subscription orders, as per the attached image, which should, according to the documentation, generate contracts.

 

However, when using the query available at https://shopify.dev/apps/subscriptions/contracts#query-the-available-contracts-on-a-store that should bring all contracts available in the store, it returns without errors but empty see:

 

To simplify I am attaching an image of the executed query.
