# Incompatible workspace

### **Explanation**

This error message arises when attempting to load a Theia workspace which was saved using Theia3D v2023 or earlier, which are not directly supported. These workspaces cannot be loaded due to incompatibilities in the models from early versions of Theia3D relative to newer versions.

### **Possible Solutions**

To obtain Theia workspaces that are compatible with current Theia3D releases, the raw data (videos and camera system calibration) must be reprocessed using the current Theia3D or Theia3D Batch release. This data can be handled in the same manner as any new data.

{% hint style="info" %}
If the original raw data used to produce the old workspaces is no longer available, it can be extracted from the old workspaces using the [Convert Workspaces](/axiom-v2025/theia3d-documentation/theia3d-batch/file-menu.md#convert-workspaces) tool within Theia3D Batch.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.theiamarkerless.com/axiom-v2025/troubleshooting/error-messages/load-workspace-errors/incompatible-workspace.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
