This might be the result of a mismatch between Elasticsearch client versions. We certify our system with ES client version 6.7.1 (we document that here: Supported Client Drivers | Stardog Documentation Latest) and it looks like you are using version 7.13.4. Perhaps they dropped support for a method that we are calling. Let me know if reverting to the older client is not a viable option for you.
