End with double-quote string problem

[yukihane]

I am trying to emulate OpenID Connect UserInfo Error Response, putting on following yaml, but it is not working as expected.

- response:
    status: 401
    headers:
      WWW-Authenticate: 'error="invalid_token"'

It looks that GroovyClassLoader#parseClass() throws exception:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
data\userinfo.get.yaml: 1: unexpected char: '"' @ line 1, column 27.
   """error="invalid_token""""

I think it works well to escepe double-quote:
