Swagger Compliance Assertion is failing

I am using Ready API 1.8.5.

Created project with Open API 2.0.

I am trying to validate the JSON response for Swagger Compliance Assertion, and getting the below error.

'Failed to find resource for [testperson] in Swagger definition.

Note :- the specification used to create a project has testperson.

Can I have a groovy script to test the 'Swagger Compliance Assertion'.
