Trying to Batch Update

Batch update in cloud gets me this , even copy pasting the same data.

Internal Error
System.InvalidOperationException: Type is not expected, and no contract can be inferred: Manager.Model.Object
   at ProtoBuf.Internal.ThrowHelper.ThrowInvalidOperationException(String message, Exception innerException)
   at ProtoBuf.Meta.TypeModel.ThrowUnexpectedType(Type type, TypeModel model)
   at ProtoBuf.Meta.TypeModel.DeepCloneFallback(Type type, Object value)
   at ProtoBuf.Meta.TypeModel.DeepClone[T](T value, Object userState)
   at ManagerServer.HttpHandlers.Businesses.Business.BatchOperations`1.InnerPost()
   at ManagerServer.HttpHandlers.Template.Post()
   at ManagerServer.HttpHandlers.HttpHandler.ProcessRequest()

Exactly what did you do to trigger the error message? In other words, at what point in the Batch Update process did it appear?

Same here:

After clicking [NEXT].

The last part, when I can get the change to check the differences.

I created a clone of the company as well and test it there as well.
Same thing.
Tried with updates, nothing. Tried copying and pasting the same data, nothing again.

I moved this to bugs.

Fixed in the latest version (20.7.71)
