Briefly, this error occurs when Elasticsearch receives a data package that exceeds the maximum allowed size. This could be due to a large document or a bulk request. To resolve this issue, you can either increase the maximum allowed package size in the Elasticsearch configuration or reduce the size of the data being sent. If you’re sending bulk requests, consider breaking them down into smaller chunks. If it’s a large document causing the issue, you may need to restructure your data to reduce its size.
