Elasticsearch version: 7.0.0
I can not reproduce the problem.
My system is frequently sync db data to Elasticsearch server through bulk method.
The proccess will do update/create/delete in bulk body.
I'm using client->bulk($params); to send the request to es server, but sometimes the document will not be updated. But the response['error'] is false.
There is no exception or error message.
Do someone has the same problem?
