Hi, I am encountering error from \_bulk endpoint but I can't solve since the error message sent by ES is null. I am calling the \_bulk endpoint via ES REST API.

Here is a snippet of the stacktrace I am getting:  
`HTTP/1.1 500 Server Error{"message":null}	at org.elasticsearch.client.RestClient$1.completed(RestClient.java:354)	at org.elasticsearch.client.RestClient$1.completed(RestClient.java:343)	at org.apache.http.concurrent.BasicFuture.completed(BasicFuture.java:119)	at org.apache.http.impl.nio.client.DefaultClientExchangeHandlerImpl.responseCompleted(DefaultClientExchangeHandlerImpl.java:177)	at org.apache.http.nio.protocol.HttpAsyncRequestExecutor.processResponse(HttpAsyncRequestExecutor.java:436)	at org.apache.http.nio.protocol.HttpAsyncRequestExecutor.inputReady(HttpAsyncRequestExecutor.java:326)	at org.apache.http.impl.nio.DefaultNHttpClientConnection.consumeInput(DefaultNHttpClientConnection.java:265)	at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:81)	at org.apache.http.impl.nio.client.InternalIODispatch.onInputReady(InternalIODispatch.java:39)	at org.apache.http.impl.nio.reactor.AbstractIODispatch.inputReady(AbstractIODispatch.java:114)	at org.apache.http.impl.nio.reactor.BaseIOReactor.readable(BaseIOReactor.java:162)	at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvent(AbstractIOReactor.java:337)	at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvents(AbstractIOReactor.java:315)	at org.apache.http.impl.nio.reactor.AbstractIOReactor.execute(AbstractIOReactor.java:276)	at org.apache.http.impl.nio.reactor.BaseIOReactor.execute(BaseIOReactor.java:104)	at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:588)	at java.lang.Thread.run(Thread.java:745)`

I think you should see a stacktrace in elasticsearch server logs. Could you paste it here?
