Configure trigger for a function in project.yml

I’m not able to configure a trigger from the project.yml file. It doesn’t throw any error when deploying, it just doesn’t add the trigger. I then need to do it manually from the browser.

Heres is my project.yml file

packages:
  - name: interpolate-data
    functions:
      - name: main
        environment:
          USER: '${USER}'
          PASSWORD: '${PASSWORD}'
        limits:
          timeout: 800000
          memory: 256
        runtime: go:1.17
        triggers:
          - name: every-hour
            sourceType: scheduler
            sourceDetails:
              cron: '0 * * * *'
