Briefly, this error occurs when Elasticsearch tries to update or add an index template for an index pattern that doesn’t exist or is null. This could be due to a misconfiguration or a programming error. To resolve this issue, you can check the index pattern you’re trying to update or add. Make sure it exists and is not null. If it’s a programming error, review your code to ensure you’re passing the correct index pattern. If it’s a configuration issue, correct the configuration to point to the right index pattern.
