[mongodb-user] MongoDb C# driver version 3.4.0 error

[Сергей Барков]

Hello ! On my mongo db c# application I have updated mongo c# driver
version from 3.3.0 to 3.4.0 and have received that reply from my web
service:

"Error": "Unsupported filter: (Convert({document}{Time}) < 05.12.2016 16 <callto:05.12.2016 16>:03:39).".


This is my code:

Expression<Func<Message, bool>> query = x => x.id == Id &&
x.Time < transportTime && x.Time > errorTime &&
x.Lat > 0 && x.Long > 0 &&
x.Liters > 0;

var item = collection.Find(query).SortByDescending(x => x.Time).Limit(1).FirstOrDefault();


I appreciate any feedback you may have.

3.3.0 to 3.4.0 and have received that reply from my web service:

Hi,

Are you referring to the MongoDB server version 3.4.0
<https://docs.mongodb.com/manual/> ? As the current latest MongoDB C#/.Net
Driver is only at version 2.3.x
<http://mongodb.github.io/mongo-csharp-driver/2.3/>.

See also MongoDB C#/.Net driver compatibility chart
<https://docs.mongodb.com/ecosystem/drivers/csharp/#mongodb-compatibility>
to check whether your current MongoDB C# driver is compatible with your
MongoDB server version.

Try to simplify your query by removing some of the filter fields to find
the exact problem. For example, only use filter x.Time < transportTime and
see whether you’re still getting an error.

Could you provide the following information:

- MongoDB .Net driver version
- An example MongoDB document to find out the Time field type.
- The value of filter variables transportTime and errorTime

Regards,

Wan.

If x.Time is a DateTime and transportTime is a Nullable<DateTime> this
could be the same issue as this ticket:
