swagger_validation.js reports error for DoorResURI.swagger.json

[Kwanghyuk-Kim]

When I run schema_validation.js with below resource model, it seems to report error.
https://github.com/openconnectivityfoundation/IoTDataModels/blob/master/DoorResURI.swagger.json

Can I know the reason of it ?

I have copied DoorResURI.swagger.json to door.json on the local pc.
and run below command,

hyuki@hyuki:~/git/C2C/mytest$ node ./tools/schema_validation.js -i ./door.json
input: ./door.json
/DoorResURI
get
200
schema_id : Door
example : { rt: [ 'oic.r.door' ],
if: [ 'oic.if.a', 'oic.if.baseline' ],
openState: 'Open',
openDuration: 'P0Y0M0DT2H25M5S',
openAlarm: true }
schema or x-example does not exist

To trace the error, I have added throw(error) below the log related with "schema or x-example does not exist".

And it provides me the callstack below.

/home/hyuki/git/C2C/mytest/tools/schema_validation.js:128
throw(err);
