shop metafield with a storefront token

Hi,
It started happening with the last couple of stores we created.

In previous stores, we created a private app with storefront access, and made the metafields visible through metafieldStorefrontVisibilityCreate. With the last couple of stores we noticed that mutation answers with Definition not found.
We know the metafields are correct because with the Admin API we can see them.

Here´s the response given by the metafieldStorefrontVisibilityCreate mutation:

{“data”:{“metafieldStorefrontVisibilityCreate”:{“metafieldStorefrontVisibility”:null,“userErrors”:[{“field”:[“input”],“message”:“Definition not found.”}]}},“extensions”:{“cost”:{“requestedQueryCost”:10,“actualQueryCost”:10,“throttleStatus”:{“maximumAvailable”:2000.0,“currentlyAvailable”:1990,“restoreRate”:100.0}}}}
