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 this error message:

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

when using Java API Client, this could happen if the underlying apache http client has been closed.

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 somewhere by mistake, most likely, an exception has occurred and caused the apache client to shut down (before you start getting CancellationException).
