I have suddenly started getting this ? what is happening here.
I don't have action=>update in config file

[elasticforme (Sachin)]

Fixed.

I had a one config file running every five min pulling data from database and inserting in to Elasticsearch
I had a another config file which was running once a hour and pulling different data and updating same index that I had created before. with same document_id. and both config was on same pipeline

I created two separate pipeline and error has gone away.
