Briefly, this error occurs when Elasticsearch is unable to serialize the result of a job, possibly due to complex data structures or incompatible data types. To resolve this issue, you can try the following: 1) Simplify your data structure, avoid using complex nested objects. 2) Ensure that your data types are compatible with Elasticsearch’s serialization process. 3) Check your Elasticsearch version, as some versions may have bugs related to serialization. 4) If the error is related to a specific field, consider excluding it from the job or transforming it into a compatible format.
This guide will help you check for common problems that cause the log ” [” + jobId + “] Error serialising result ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: plugin.
Log Context
Log “[” + jobId + “] Error serialising result” classname is JobRenormalizedResultsPersister.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
public void updateResult(String id; String index; ToXContent resultDoc) {
try (XContentBuilder content = toXContentBuilder(resultDoc)) {
bulkRequest.add(new IndexRequest(index).id(id).source(content));
} catch (IOException e) {
logger.error(() -> "[" + jobId + "] Error serialising result"; e);
}
if (bulkRequest.numberOfActions() >= BULK_LIMIT) {
executeRequest();
}
}
