Java API Client throwing AlgoliaRuntimeException

The AlgoliaRuntimeException is thrown when an error occurred during serialization/deserialization or data processing. More on this in our Handling Exceptions documentation.

If you're getting the error message below when using the Java API Client, it could be that the underlying apache http client has been closed.:

com.algolia.search.exceptions.AlgoliaRuntimeException: 
java.util.concurrent.CompletionException: 
java.util.concurrent.CancellationException: Request execution cancelled

There are two workarounds you can try:

1. Reinstantiate the client when an exception like java.util.concurrent.CancellationException: Request execution cancelled is thrown.
2. If you use Java 11, use algoliasearch-java-net instead.

If you didn’t close the client manually by mistake, most likely, an exception has occurred and caused the apache client to shut down (before you start getting CancellationException).
