After upgrading the C# driver in our project from 2.8.1 to 2.10.1, we can no longer write changes to the database. We don't use sessions / transactions and have made no changes in our code. Downgrading to 2.8.1 resolves the issue. I've also confirmed the problem exists with 2.9.0 and 2.9.3.
The error is the following:
A write operation resulted in an error.
Transaction numbers are only allowed on a replica set member or mongos ---> SimpleInjector.ActivationException: The registered delegate for type Service threw an exception. A write operation resulted in an error.
Transaction numbers are only allowed on a replica set member or mongos ---> MongoDB.Driver.MongoWriteException: A write operation resulted in an error.
Transaction numbers are only allowed on a replica set member or mongos ---> MongoDB.Driver.MongoBulkWriteException`1[Kolonel.Gateway.Model.ProcessInstance]: A bulk write operation resulted in one or more errors.
Transaction numbers are only allowed on a replica set member or mongos
at MongoDB.Driver.MongoCollectionImpl`1.BulkWrite(IClientSessionHandle session, IEnumerable`1 requests, BulkWriteOptions options, CancellationToken cancellationToken)
