sentinl: Sentinl reports don't snapshot the correct page

Hi

I’m using elasticsearch + kibana 5.5.2 (with searchguard), i have installed sentinl on kibana and everything seems to work fine except the reports snapshot

Description of the issue:

I create a reporter and set the action (report action) for a link of a dashboard for example “http://127.0.0.1:5601/app/kibana#/dashboard/CC-Test-Dashboard” and when the report is generated i expect to receive a snapshot of the dashboard but i only get a snapshot of main kibana page (discover tab)

next is my sentinl configuration and example of reporter configuration, can you help me?

Thanks

Sentinl configuration at kibana.conf

sentinl:
  settings:
    email:
      active: true
      host: smtp.hdi.tvcabo
      ssl: false
      timeout: 10000  # mail server connection timeout
    report:
      active: true
      tmp_path: /tmp/
      search_guard: true

Reporter example of configuration (some fields are omitted and the dashboard url is just an example not the real link used)
