.Net MongoDB.Driver on Azure Cosmos DB error

Question

IList<FilterDefinition<Family>> filters = new List<FilterDefinition<Family>>();
var filter = Builders<Family>
    .Filter.Eq(e=>e.id, "Andersen.1");
filters.Add(filter);

var filterPartiion = Builders<Family>
    .Filter.Eq(e => e.LastName, "Andersen");
filters.Add(filterPartiion);

var update = Builders<Family>.Update
    .Set<Boolean>(e=>e.IsRegistered, true);

var searchOn = Builders<Family>.Filter.And(filters);

collection.UpdateOne(searchOn, update);

Using .net MongoDB.Driver on Azure Cosmos DB, I would like to do an update on the IsRegistered element of the document based on the the filter of id="Andersen.1" and LastName="Andersen", in which LastName is partition key. I am new to MongoDB, is my code correct?

I got an error:

"query in command must target a single shard key"
