Getting a 500 code error when deploying python function with a trigger

When I execute doctl serverless deploy . on my python function, I’m getting an error code 500.

Deployed functions ('doctl sls fn get <funcName> --url' for URL):
  - runner/scrape
Failures:
Error: While deploying while deploying trigger 'daily-trigger': Request failed with status code 500

However, when I remove the trigger from my project.yml, the project uploads fine.

My project.yml looks like the following (minus some credentials):

parameters: {}
environment: {}
packages:
  - name: runner
    shared: false
    environment: {}
    parameters: {}
    annotations: {}
    functions:
      - name: scrape
        binary: false
        main: ""
        runtime: python:3.11
        web: false
        webSecure: false
        parameters: {}
        environment:
          ENVIRONMENT: prod
        annotations: {}
        limits: {}
        triggers:
          - name: daily-trigger
            sourceType: scheduler
            sourceDetails:
              cron: "0 2 * * *"

What am I doing wrong?
