NullReferenceException results from the following code after upgrade to v2.4.2:
System.NullReferenceException occurred Message: Exception thrown: 'System.NullReferenceException' in MongoDB.Bson.dll Additional information: Object reference not set to an instance of an object.
Here's our C# code:
public class FxRateDataDb : IFxRateDataDb
{
[BsonId]
public string Id { get; set; }
}
public class MongoDbCollection<T, TId> : IDbCollection<T> where T : IId<TId>
{
private readonly IMongoCollection<T> _mongoCollection;
public async Task ReplaceOneAsync(T item, bool upsert)
{
await _mongoCollection.ReplaceOneAsync(x => Equals(x.Id, item.Id), item, new UpdateOptions {IsUpsert = upsert}); // NullReferenceException
}
}
