Does not insert OwnsOne columns

[adminnz]

My postgresql database has:

CREATE TABLE events
(
    ...
    error_details JSONB NULL
    ...
)

In my model i have:

modelBuilder.Entity<Event>().OwnsOne(x => x.ErrorDetails, builder => builder.ToJson("error_details"));

Which when using the ef core Add(..) or Update(..) methods correctly serializes the nested object to json and stored.

But using Upsert(...) the resulting sql does not produce the error_details column.

When i look at the ef core EntityType model, the error_details is not listed in the GetProperties(), so I don't know where it is meant to be fetched from.

I've also experienced this after using the new .ToJson() EF API.

Worked flawlessly before when using the .HasColumnType("jsonb")

I took a peek at it, and it looks as the ToJson() columns are treated very differently, almost as a relationship of some kind. To properly handle them, it would be needed to dig deeper into EF Core's code, and pull out the code they use to serialise this data into JSON, as I'm not sure if just passing an object would work, as it did before.

Unfortunately I didn't work with these columns, and don't have the time myself for that deep investigation, but would appreciate any help on this
