Cannot return JSON from ScriptRunner REST Endpoint

[nojini]

Hi,

I'm trying to get the results of a REST endpoint, but it doesn't return anything (204 No Content) when I run it in the browser using <Jira base URL>/rest/scriptrunner/latest/custom/countryQuery. Printing the JSON I'm trying to return works and it's in the right format. 

Here's the expected result:

{"id":"BRA","name":"Brazil","region":{"id":"LCN","iso2code":"ZJ","value":"Latin America & Caribbean "},"incomeLevel":{"id":"UMC","iso2code":"XT","value":"Upper middle income"},"capitalCity":"Brasilia","longitude":"-47.9292","latitude":"-15.7801"}

Here's my code:

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.json.JsonBuilder
import groovy.transform.BaseScript
import groovyx.net.http.ContentType
import groovyx.net.http.HTTPBuilder
import groovyx.net.http.Method
import static groovyx.net.http.ContentType.JSON
import static groovyx.net.http.Method.GET

import org.apache.log4j.Level
import org.apache.log4j.Logger

import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
import javax.ws.rs.core.MediaType

@BaseScript CustomEndpointDelegate delegate

countryQuery(httpMethod: "GET") { MultivaluedMap queryParams -> 
  log = Logger.getLogger("com.acme.workflows")
  log.setLevel(Level.DEBUG)

  def http = new HTTPBuilder("http://api.worldbank.org")

  http.request(GET) {
    uri.path = "/v2/country/br"
    uri.query = [format: "json"]
    response.success = { resp, json ->
      log.info("Success!")

      def result = [
        id: json[1][0]["id"],
        name: json[1][0]["name"],
        region: json[1][0]["region"],
        incomeLevel: json[1][0]["incomeLevel"],
        capitalCity: json[1][0]["capitalCity"],
        longitude: json[1][0]["longitude"],
        latitude: json[1][0]["latitude"]
      ]
      log.info("\n" + new JsonBuilder(result).toString())
      return Response.ok(new JsonBuilder(result).toString()).build()
    }

    response.'400' = { resp, json ->
      log.warn('Failed: Bad Request')
      if (json) {
        log.warn("Message: " + json)
      }
    }

      response.failure = { resp, json ->
        if (json) {
          log.warn("Message: " + json)
        }

        log.warn("Failed: JSON response" + json)
        log.warn("Status: " + resp.getStatus())
        log.warn("Status Line: " + resp.getStatusLine())
        log.warn("Data: " + resp.getData())
        log.warn("Params: " + resp.getParams())
      } 
    }
  log.setLevel(Level.WARN)
}

Please help, thanks.

Removing the last line worked.

log.setLevel(Level.WARN)
