             Summary: HTTP 500 error when retrieving Entity via connection
                 Key: USERGRID-1304
                 URL: https://issues.apache.org/jira/browse/USERGRID-1304
             Project: Usergrid
          Issue Type: Bug
          Components: Stack
    Affects Versions: 2.1.0
            Reporter: David Johnson


From the Usergrid mailing list:

I've noticed that the errors Usergrid returns seem somewhat
inconsistent. For example, when attempting to GET an entity that doesn't
exist directly from the collection (omitting org and app from path for
clarity):

GET /things/ferrari

will return an error "entity_not_found", but attempting to GET the same
entity through a connection where I "own" the entity:

GET /users/me/owns/things/ferrari

will return an "uncaught" error, with error_description "Internal Server
Error."

Is this intentional? I was expecting to get an "entity_not_found" error
in both cases, as I think this would be a pretty common situation to
have in a system where entities are created and deleted dynamically.

(If /things/ferrari actually exists and I own it, both queries return it
as expected, so that's cool.)

If I've understood the design intent behind Usergrid correctly, these
connections are extremely important because I can map permissions to
them. Therefore it's not always possible to access objects directly
under the collection, as the user may only have permission to access
objects through a connection (e.g. "owns"). I like this scheme a lot,
it's simple, intuitive, yet powerful.


Here are curl commands that reproduce the behavior:

curl -X POST "http://localhost/udwc/brikoleur/token" -d '{ "grant_type"
…

: "password",  "username" : "abogdanov", "password" : "thepassword" }'

{"access_token":"YWMtpgdKYDbyEeaD2zHg-adLzwAAAVWSPvYGkxL-sP9RrdRTbAGgQJijcOXcApE","expires_in":604800,"user":{"uuid":"2349d142-317a-11e6-9322-080027cf389a","type":"user","name":"Alexander
