I am trying to get my Active choice parameter drop down options from curl response.

Below is the code i pasted in Active choice parameter

import groovy.json.JsonSlurper

withCredentials([usernamePassword(credentialsId: 'cred-id', usernameVariable: 'username', passwordVariable: 'var')]) {
    try {
        if (appname == 'app1') {
            def process = "curl -u $USERNAME:$PASSWORD -X GET 'https://<app url>/api/v1/repos/<repo path>/tags?pageSize=10&count=false&includeManifests=false' -H 'accept: application/json' -H 'X-Csrf-Token: <token>' -H 'Content-Type: application/json'".execute()
            process.waitFor()
            def output = process.in.text.trim()
            def jsonSlurper = new JsonSlurper()
            def object = jsonSlurper.parseText(output)

            def option_list = object*.name
            return option_list
        } else {
            return ["aminelse"]
        }
    } catch (Exception e) {
        return[e]
    }
}

after saving if i click on build with parameter the options am getting is like below

[object Object]
