Briefly, this error occurs when there’s an attempt to stop the Elasticsearch Watcher service, but it’s not in a state that allows it to be stopped. This could be because it’s already stopped, or it’s in the process of stopping. To resolve this, you can check the current state of the Watcher service. If it’s already stopped, no action is needed. If it’s in the process of stopping, wait for it to complete. If it’s active, try stopping it again. If the problem persists, consider restarting the Elasticsearch service.
