Briefly, this error occurs when Elasticsearch cannot find the specified index lifecycle management (ILM) policy. This could be due to the policy not being created, being deleted, or a typo in the policy name. To resolve this issue, you can check if the policy exists using the Get Lifecycle Policy API. If it doesn’t exist, you need to create it using the Put Lifecycle Policy API. If the policy name is incorrect, correct it in your request. Also, ensure that the ILM feature is enabled in your Elasticsearch setup.
