exists, id, hasPendingWrites warning from useDocument

[gwendall]

I call useDocument to get some data: const { data } = useDocument<Items>("items/123");.
I get the following warning: [get-document] warning: Your document, 123 is using one of the following reserved fields: [exists, id, hasPendingWrites]. These fields are reserved. Please remove them from your documents.

The actual firestore document doesn't contain these fields.
What do I do wrong ? How can I get the actual saved document ?

#46 may be a solution.

If you use an id field in any of your documents, I suggest removing that. Firestore IDs should be confined to the ID of the document itself. If you want to include an ID field in the document, I recommend naming it something more specific.
