This error occurs when you have changed the embedder model after previously upload a document to a workspace that was embedder with some previous model.

In either case, Open the workspace's settings and go to "Vector Database" and click "reset vector database" and you should be able to both embed documents and send responses.

This issues occurs when you change the embedder because your embedded prompt dimensions and the vector database vector column have different dimensions.
