Briefly, this error occurs when Elasticsearch fails to load a specific model task due to issues like incorrect model ID, insufficient permissions, or network connectivity problems. To resolve this, you can verify the model ID and ensure it’s correct. Check the user permissions to ensure they have the right to access the model. Lastly, ensure that the Elasticsearch cluster is up and running and there are no network issues preventing the task from loading.

        if (task.isStopped()) {
                () -> format(
