Storage write rejected - version check failed

[justinbalaguer]

Suddenly have this error when using WriteStorageObjectsAsync

code is similar to sample here https://heroiclabs.com/docs/nakama/concepts/storage/collections/#conditional-writes

var saveGame = "{ \"progress\": 50 }";

var objectIds = await client.WriteStorageObjectsAsync(session, new [] { 
  new WriteStorageObject
  {
      Collection = "saves",
      Key = "savegame",
      Value = saveGame,
      Version = "<version>"
  }
});

Tried restarting the server and deleting saved account and storage still having that error.

@justinbalaguer What are you passing as the version? Is it the value you receive when you get the storage objects, and is your storage key experiencing concurrent writes?

[justinbalaguer]

collectionObject is from a ScriptableObject

@justinbalaguer this error means that you are passing a value of Version that is different than what the server has for your data. The most likely cause is that you aren't passing the version from the acknowledgment of your last write or "*" if it's your first write:

Closing because this doesn't seem to be an SDK issue. If you can fully reproduce a bug on the server please file it on our Nakama repo: https://github.com/heroiclabs/nakama
