Fix IllegalStateException

✅ Solution

IllegalStateException in Elasticsearch typically arises from attempting to perform an operation on an object that is not in the appropriate state, such as trying to read from a closed stream or accessing a search context that is no longer valid (e.g., post Point-In-Time expiration). To resolve this, ensure resources are properly initialized and managed (e.g., manage PIT lifecycles explicitly), and add robust error handling with appropriate logging around resource-intensive operations, especially those involving time-sensitive Elasticsearch contexts. For PIT-related issues ensure the PIT ID is valid and still accessible at the time of the request, retrying with a fresh PIT if necessary.
