I have an index say test_index which I create using a template.
Everything was working fine until I tried to update the template, delete the index and create the index again with the updated template. (I did these steps successfully a couple of times).
I use the BulkRequestBuilder java API for indexing.
The error I get is
org.elasticsearch.action.ActionRequestValidationException: Validation Failed: 1: source is missing
Appreciate your help to resolve this issue please.
