ElasticSearch MapperParsingException对象映射

我在下面有一篇关于ElasticSearch的文章,我尝试将这个例子放在我的引擎上.

例:

curl -XPUT 'elasticsearch:9200/twitter/tweet/1' -d '{
    "user": "david",
    "message": "C'est mon premier message de la journée !",
    "postDate": "2010-03-15T15:23:56",
    "priority": 2,
    "rank": 10.2
}'

我尝试通过bash文件发送此信息(我使用Putty),但我有这个错误:

{"error":"MapperParsingException[object mapping for [tweet] tried to parse as object, 
  but got EOF, has a concrete value been provided to it?]","status":400}

我也尝试用"cat -e tweet.sh"看到一个错误,但我不明白为什么我有这个错误.

提前致谢.
