Hey there,
in #1772 the IConvertible Exception is gone but now if the filter is set, it returns string empty. This is because in line 790
the comparison to DateOnly is missing and then in line 810, string emtpy is returned

So the Fix would be to add DateOnly type comparison :

else if (column.FilterPropertyType == typeof(DateTime) || column.FilterPropertyType == typeof(DateTime?) || column.FilterPropertyType == typeof(DateTimeOffset) || column.FilterPropertyType == typeof(DateTimeOffset?) || column.FilterPropertyType == typeof(DateOnly?))

and to use the value instead of parsing it in line 802

like return $"{property} {odataFilterOperator} {(column.FilterPropertyType == typeof(DateOnly?) ? value : DateTime.Parse(value, CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.RoundtripKind).ToString("yyyy-MM-ddTHH:mm:ss.fffZ", CultureInfo.InvariantCulture))}";

Thank you,
best regards
