# Error during template save with Spotfire 12

When saving a template from the LiveDesign Connector in Spotfire 12.0.X, an error related to a "Disposed" state can be raised and prevent from saving.

## Details

If you create a template from scratch using the LiveDesign Connector in Spotfire version 12.0.X, then go in the **Save as Template** page and click on **Save** in order to save your template in the library, two "LiveDesign Connector Error" notifications are raised:

- An error occurred during save current document as template
- An error occurred during <Template Name> save

```
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.Serialization.SerializationException: Attempt to read from a node that is in state 'Disposed': Spotfire.Dxp.Framework.DocumentModel.State.DisposedUndoablePropertyNodeState`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].
Object reference chain leading to the fault (closest reference first):
    Spotfire.Dxp.Application.CustomNodeStandIn.Table
    Spotfire.Dxp.Application.CustomNodeStandIn.Tables[0]
    Spotfire.Dxp.Application.CustomNodes.Nodes[1]
    Spotfire.Dxp.Application.Document.CustomNodes
 ---> System.InvalidOperationException: Attempt to read from a node that is in state 'Disposed': Spotfire.Dxp.Framework.DocumentModel.State.DisposedUndoablePropertyNodeState`1[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].
```

This is due to a Spotfire issue that prevents the regular default template (empty document) to be used as a base for saving a new document.

## Resolution

This error can be fixed by replacing the regular empty document by one specifically created for the 12.0.X version of Spotfire. It needs to be done by a Spotfire administrator following the [import library step of the installation guide](/public/docs/connector-ld-spo-admin-guides-installation#import-library) but using this [LDConnector_Spotfire_12.X.part0.zip](https://files.discngine.com/hubfs/Connector%20Installation%20Packages/LiveDesign%20Connector%20for%20Spotfire/LDConnector_Spotfire_12.X.part0.zip) file instead of the file provided in the package.
