Why does Ruby 2.3.0 JSON.parse give unexpected token error?

I have the following JSON returned in a response:

"{\n  \"notices\": [\n    {\n      \"id\": \"1234\",\n      \"projectId\": 1,\n      \"groupId\": \"55\",\n      \"createdAt\": \"2014-10-22T03:00:00.407Z\"\n    },\n    {\n      \"id\": \"1234\",\n      \"projectId\": 1,\n      \"groupId\": \"55\",\n      \"createdAt\": \"2014-10-22T03:00:00.407Z\"\n    },\n  ],\n  \"count\": 2\n}\n"

In irb for Ruby 2.3.0, when I use JSON.parse(x) on the above response, I get:

JSON::ParserError: 419: unexpected token at '],
  "count": 2
}'

even though http://jsonlint.com says it is valid JSON. What am I doing wrong?

There seems to be an issue with having a comma after the last object in your array:

\"createdAt\": \"2014-10-22T03:00:00.407Z\"\n    },\n  ],\n  \"count\": 2\n}\n"
                                                  ^ This comma

After getting rid of it, I got the parse to work as expected:

JSON.parse("{\n  \"notices\": [\n    {\n      \"id\": \"1234\",\n      \"projectId\": 1,\n      \"groupId\": \"55\",\n      \"createdAt\": \"2014-10-22T03:00:00.407Z\"\n    },\n    {\n      \"id\": \"1234\",\n      \"projectId\": 1,\n      \"groupId\": \"55\",\n      \"createdAt\": \"2014-10-22T03:00:00.407Z\"\n    }  ],\n  \"count\": 2\n}\n")
=> {"notices"=>[{"id"=>"1234", "projectId"=>1, "groupId"=>"55", "createdAt"=>"2014-10-22T03:00:00.407Z"}, {"id"=>"1234", "projectId"=>1, "groupId"=>"55", "createdAt"=>"2014-10-22T03:00:00.407Z"}], "count"=>2}
