Throws java.lang.NullPointerException when getSource

Elastic Stack Elasticsearch
1

Hi there,

When I was running a piece of code, which means to get some doc from my
index, it throws the exception java.lang.NullPointerException。
Is there anything I set wrongly? Thanks.

My code is like this:
GetResponse response = client.prepareGet(indexName, "kba", stream_id)
.execute()
.actionGet();
String body_cleansed = response.getSource().get("body_cleansed").toString();

Did you disable source in mapping?

Hi David,
I don't think so. I preserved the source option when I was creating the
indices.
I remembered that I could run this program the other days.
Is there other reasons could result in this situation?

I have checked it.
When I use prepareSearch, getSource works fine.
While when I use prepareGet, getSource throws this exception.
