Here i have saved trending_content variable in Session but not able to access it, Any thoughts please?

val land = exec(http(“Now Tab”)
.get("/now/trending_content?callback=trendingContentLoaded.store")
.check(status.is(200))
.check(bodyString.saveAs(“body”)))
.exec(session => {
// print the Session for debugging, don’t do that on real Simulations
val trending_content = session(“body”).as[String].replace(“toremoveSomething”, “”)
println(" Wooooo <<<<>>> " + trending_content)
session.set(“trendingVideoEmbed”, trending_content)
session})
.pause(1)
.exec(http(“Move to Trending Asset Deatil Page.”)
.get("/video/"+ “${trendingVideoEmbed}”)
.check(status.is(200))
.check(bodyString))
.pause(1)

It throws [ERROR] i.g.h.a.HttpRequestAction - No attribute named ‘trendingVideoEmbed’ is defined
