Field name cannot be an empty string


(Mithun) #1

Hi Team,

I am trying to transport bulk reports from a different VM (192.168.0.xxx) to Elasticsearch machine (192.168.0.xxx).
I saw the below error in /var/log/elasticsearch/elasticsearch.log

Error:

Please format your logs and code.

We can't help without knowing what you sent to elasticsearch.
