How to use C# 9.0's record feature in RavenDB?

[Arash Sabet]

I have a C# 9.0 record and when trying to save it, I get the following exception from RavenDB's client:

Raven.Server.Rachis.RachisApplyException: In ClusterTransactionDataCommand document id cannot be null, empty or white spaces as part of cluster transaction. Type:(PUT), Index:(0)

   at Raven.Server.ServerWide.Commands.ClusterTransactionCommand.ClusterCommandValidation(ClusterTransactionDataCommand command, Char identityPartsSeparator)

   at Raven.Server.ServerWide.Commands.ClusterTransactionCommand..ctor(String databaseName, Char identityPartsSeparator, String recordId, ArraySegment`1 commandParsedCommands, ClusterTransactionOptions options, String uniqueRequestId)

   at Raven.Server.Documents.Handlers.BatchHandler.HandleClusterTransaction(DocumentsOperationContext context, MergedBatchCommand command, ClusterTransactionOptions options)

   at Raven.Server.Documents.Handlers.BatchHandler.BulkDocs()

   at Raven.Server.Routing.RequestRouter.HandlePath(RequestHandlerContext reqCtx)

   at Raven.Server.RavenServerStartup.RequestHandler(HttpContext context).

The record looks like the following code snippet. Is this because a record instance is an immutable entity?

public record Model(string Id);

public record User

(

int UserId,

string Id,

string Login

) : Model(Id);

What is the solution for this problem?

Hi,

It looks like it's part of a cluster transaction.

You must set the id of the entity before saving.
