Unrecognized behavior

[Supta Biswas]

Hi,

I am trying to use "copy behavior" in this format:

{

"from" : "body",

"into" : "${{msg}}",

"using" : {

   "method" : "jsonpath",

   "selector" : "$..message"

}

}

Got error while updating this imposter-

error creating imposter: [{"code" : "bad data", "message" : "Unrecognized behavior : \"from\"" , "source" : {"from" : "body","into" : "${{msg}}","using" : {"method" : "jsonpath","selector" : "$..message"}}}].

I am using mountebank release 2.5.0 & ui testinggospels. 

TIA.
