Im trying to create an API connection in Logstash and push the data to elasticsearch. Both Elasticsearch and Logstash versions are 7.1.0. Below id the logstash file:

```auto
input {
          http_poller {
            urls => {
              test2 => {
                method => get
        user => "readonly"
            password => "mypass@123"
                url => "https://nfr.saas.appdynamics.com/controller/rest/applications?output=JSON"
                headers => {
                  Accept => "application/json"
                }
             }
            }
            request_timeout => 60
            # Supports "cron", "every", "at" and "in" schedules by rufus scheduler
            schedule => { cron => "* * * * * UTC"}
            codec => "json"
            # A hash of request metadata info (timing, response headers, etc.) will be sent here
            metadata_target => "http_poller_metadata"
          }
        }

        output {
          elasticsearch { hosts => ["localhost:9200"]
           index => "dataapi" }
          stdout { codec => rubydebug }
        }

```

I am receiving an error:

```

Im new to APIs, and I'm not sure how to simply fetch the output from the URL. Could you help me on getting this corrected? The URL works when i hit it on my browser.
