  ```
  
  get-schedule-isactive.sh
  
  ```
  #!/bin/sh
  echo "false"
  ```
  
  prefect.yaml
  ```
  definitions:
  
    work_pools:
      docker_work_pool: &docker_work_pool
        name: docker-pool
        work_queue_name: "{{ get-work-pool.stdout }}"
  
    schedules:
      every_hour: &every_hour
        cron: "0 0 * * *"
        timezone: "America/Chicago"
        active: "{{ get-schedule-isactive.stdout }}"
  
    actions:
  
      docker_build: &docker_build
        - prefect.deployments.steps.run_shell_script:
            id: get-commit-hash
            script: git rev-parse --short HEAD
            stream_output: false
        - prefect.deployments.steps.run_shell_script:
            id: get-work-pool
            script: sh utils/get-work-pool.sh
            stream_output: false
        - prefect.deployments.steps.run_shell_script:
            id: get-schedule-isactive
            script: sh utils/get-schedule-isactive.sh
            stream_output: false
        - prefect_docker.deployments.steps.build_docker_image:
            id: build-image
            image_name: "repo/image"
            tag: "{{ get-commit-hash.stdout }}"
            dockerfile: Dockerfile
  
  ```
  
  If I update the schedule in prefect-yaml like below it works fins.
  
  ```
  schedules:
      every_hour: &every_hour
        cron: "0 0 * * *"
        timezone: "America/Chicago"
        active: "false"
  
  ```
  
  Is this because of pydantic? Workarounds?
