what's wrong with ElasticSearch

[bulabula001]

when i run the opensoc-ui, and visit the site of the http://192.168.10.124:5000 . page, and then submit the topology of Bro and Sourcefire, in the site of opensoc-ui, i can see the data of the Sourcefire, but can not see the data of the Bro, and when i check the log of ES, i found the error below , i never edit the config about the bro and it is same as the sourcefire.
someone else can help me?
