[BUG] Cannot delete a model that was created with missing additional_config

[kimpepper]

What is the bug?

I have been trying to get semantic search with Bedrock set up locally using docker compose, and created a model with missing additional_config. However, I cannot delete this model as I get the following error:

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Space type must be provided in additional_config for remote text embedding model"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Space type must be provided in additional_config for remote text embedding model"
  },
  "status": 400
}

How can one reproduce the bug?

1. Create a remote model with missing additional_config
2. Try to delete the model
3. Get a validation error when trying to delete

What is the expected behavior?

The index is deleted.

Do you have any additional context?

A workaround is to delete the docker volumes and start again.
