I am using below snippet in my jenking groovy file, where I am getting null response.

def Services= sh(script: "curl -s --header "PRIVATE-TOKEN: ${gittoken}" ${url}| jq -r .${Servicename}[]", returnStdout: true)

file which I am downloading is like below.

{
  "FrameWork1": [
    "sample/sample1",
    "sample/sample2"
  ]
 
}

Basically I am getting values of Framework1

if I give below one I am getting the first value of Framework object

Working one:###############

def Services= sh(script: "curl -s --header "PRIVATE-TOKEN: ${gittoken}" ${url}| jq -r .${Servicename}[1]", returnStdout: true)
