Unable to get _schema response,

[cyf992002]

**When I created a json schema using

http put http://a:a@127.0.0.1:8888/db/_schemas/address < address_schema.json

I can see the schema was created successfully in Mongo DB. But when I tried to get the schema back using http get http://a:a@127.0.0.1:8888/db/_schemas/address I got a 500 error**

{ "_embedded": { "rh:exception": [ { "exception": "java.lang.NullPointerException" } ] }, "_links": { "self": { "href": "/db/_schemas/address" } }, "http status code": 500, "http status description": "Internal Server Error", "message": "Error handling the request, see log for more information" }
