Log Context

Log “Unsupported operation: parsed aggregations are null” class name is AggProvider.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 throw new ElasticsearchException(parsingException);
 }
 } else if (parsedAggs == null) {
 // This is an admittedly rare case but we should fail early instead of writing null when there
 // actually are aggregations defined
 throw new ElasticsearchException("Unsupported operation: parsed aggregations are null");
 }
 // Upstream we already verified that this calling object is not null; no need to write a second boolean to the stream
 parsedAggs.writeTo(out);
 }
 }
