bug EntityFramework.Ydb: Status: GenericError

[KirillKurdyukov]

An exception of type 'Ydb.Sdk.Ado.YdbException' occurred in System.Private.CoreLib.dll but was not handled in user code
Status: GenericError, Issues:
[1030] Error: Type annotation
    [0] (3:1) Error: At function: RemovePrefixMembers, At function: PersistableRepr, At function: SqlProject, At function: SqlProjectItem
        [0] (3:8) Error: At function: Coalesce
            [0] (3:8) Error: uncompatible coalesce types, first type: Optional<Decimal(35,9)>, second type: Double

Repro:

var query = dbContext.Packets
    .Where(_ => _.A > startTimestamp && _.A < endTimestamp)
    .OrderByDescending(_ => _.A)
    .AsQueryable();
var bytesSum = await query.Select(_ => _.B).SumAsync();

public class PacketSet
    {
        public Guid Id { get; set; }
        public UInt64 A { get; set; }
        public decimal B { get; set; }
    }

I think error is in query:
SELECT COALESCE(SUM(p.B), 0.0)
FROM Packets AS p
WHERE p.A > @__startTimestamp_0 AND p.A < @__endTimestamp_1

can not convert 0.0 double to decimal

@KirillKurdyukov Where do you think it would be better to look at the code to fix it?

[KirillKurdyukov]

This class has some problem. It doesn't convert decimal to the const type Decimal.
