Need help with train delay script

Configuration

Hi, i would try to make an train delay script with the dutch railway NS integration. when i execute the script i get an error message:ValueError: Template error: strptime got invalid input 'unknown' when rendering template '{{ (strptime(actual_time, "%H:%M") - strptime(planned_time, "%H:%M")).total_seconds() / 60 }}' but no default was specified

i have tried to add now() to the actual_time and planned_time but with no succes can somebody help me to made this script work when there is an train delay? the default message is working correct.
here is my script:

alias: Train delay
sequence:
  - variables:
      planned_time: >-
        {{ states("sensor.train",
        "departure_time_planned") }}
      actual_time: >-
        {{ states("sensor.train",
        "departure_time_actual") }}
      delay: >-
        {{ (strptime(actual_time, "%H:%M") - strptime(planned_time,
        "%H:%M")).total_seconds() / 60 }}
  - choose:
      - conditions: "{{ delay > 0 }}"
        sequence:
          - service: notify.mobile_app_iphone_van_willem
            data:
              message: The train is delayed by {{ delay }} minutes
              data:
                push:
                  sound:
                    name: default
                    critical: 1
                    volume: 1
          - if:
              - condition: state
                entity_id: person.willem
                state: Thuis
            then:
              - service: sonos.snapshot
                data:
                  with_group: true
                  entity_id: media_player.studeerkamer
              - service: media_player.volume_set
                data:
                  volume_level: 0.11
                target:
                  entity_id: media_player.studeerkamer
              - service: tts.cloud_say
                data:
                  cache: false
                  entity_id: media_player.studeerkamer
                  language: nl-NL
                  message: >-

                    minuten
              - delay:
                  hours: 0
                  minutes: 0
                  seconds: 1
                  milliseconds: 0
          - service: sonos.restore
            data:
              with_group: true
              entity_id: media_player.studeerkamer
    default:
      - service: notify.mobile_app_iphone_van_willem
        data:
          message: The train is on time and leaves on {{ actual_time }}
mode: single

shouldn’t this:

sequence:
  - variables:
      planned_time: >-
        {{ states("sensor.train","departure_time_planned") }}

be

{{ state_attr("sensor.train","departure_time_planned") }}

and same for actual_time?

Also, what happens when you put it into developer tools ➜ template?

I have made an automation that is working.
