Querying a field inside a nested document, make the query fail

Hello,
I'm trying to query in a MongoDB with Metabase 1.45.2. If I select, like in the image, at least one field inside the nested document.

It fails like this:

[111a1248-72c2-4544-9669-cdf8147fd777] 2023-01-18T14:19:42+01:00 ERROR metabase.query-processor.middleware.catch-exceptions Errore elaborazione query: Errore nell'esecuzione della query

In other topics I found the issue "Error reducing result rows: null" was solved by upgrading, so I did it from 1.44.6 to 1.45.2, but it' still present.
How to solve?
