httpRequest does not return result in parameters's Groovy script

[Gajanan Mahajan]

If I make following http request in pipeline code it returns result for `response.status`

    def response = httpRequest authentication: '<some-auth>', url: '<some-url>'

However if same code is passed to Groovy script of pipeline parameter, it returns nothing and also no error is seen.

Please help on how I can make it to work in Grooy script of pipeline parameter
