Failed to derive xcontent from org.elasticsearch.common.bytes.BytesArray@0

Question

My curl query works

curl -v -XGET 'http://localhost:9200/entityitem/5/_mget' -d '{"ids" : ["5000027585", "5000027615"]}'

but when I use the rest client to do GET query

http://localhost:9200/entityitem/5/_mget?source={"ids" : ["5000027585", "5000027615"]}

I get the following error

Failed to derive xcontent from org.elasticsearch.common.bytes.BytesArray@0

Answer 1

If you get this while following the kibana tutorial you may be trying to import the shakespeare.json file. You probably downloaded to downloads folder and are running the import command in another folder. Move the input file to the current directory...

mv ~/Downloads/shakespeare.json .

and run your curl xput command to import the shakespeare data.

curl -XPUT localhost:9200/_bulk --data-binary @shakespeare.json

Yeah. It's an issue.

I just fixed it yesterday. See https://github.com/elasticsearch/elasticsearch/issues/4892
