Unable to deserialize object: The deserializer threw an exception ,in Scaleout Object Browser

[Anuja Sahu]

I'm trying to store the data in ScaleOut and I am able to save the String value. And I am able to validate the stored data in the ScaleOut through ScaleOut Object Browser.
But when I am trying to store the class object in ScaleOut, code is successfully executing. But when I'm trying to validate the stored data in the scaleout through ScaleOut Object Browser, I'm getting the object deserialization error.

Error:


System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.Serialization.SerializationException: There was an error deserializing the object . The data at the root level is invalid. Line 1, position 1. ---> System.Xml.XmlException: The data at the root level is invalid. Line 1, position 1.

Hi Anuja,

It looks like you've configured the Object Browser to use an XML deserializer, but the object wasn't serialized as XML--the XML parser didn't get past the first character. If you look at the raw object contents (in the Contents tab there in your screenshot), does it look like XML?

By default, the ScaleOut APIs perform binary serialization. So in your app, you'll want to look at your cache configuration to make sure that you've set it up to perform XML serialization. The exact call will depend on the client library that you're using:

• Traditional .NET NamedCache library: NamedCache.SetCustomSerialization
• Newer Scaleout.Client NuGet package: CacheBuilder.SetSerialization (more info)
• Traditional Java NamedCache: NamedCache.setCustomSerialization
• Newer ScaleOut Client Library for Java: CacheBuilder.SetCustomSerialization (more info)

If you didn't intend for the Object Browser to perform XML deserialization, you can configure it in the "Tools > Default Serialization" menu item, or you can specify how the Object Browser does deserialization on a cache-by-cache basis: just right-click on the cache in question and select "Deserialization..." from the context menu.
