Github Actions workflow not triggered although schedule should trigger the job - github

Question

I'm trying to auto-assign issues and PRs in Github from a Github Actions workflow. The respective steps work fine when an issue / a PR is opened. So this trigger is fine.
Recently I added Dependabot to my repo. Since Dependabot cannot access my secrets I cannot assign any issue in a Dependabot-triggeres pipeline. So I just thought I run this pipeline with a scheduler one per day to "clean up" every issue and PR which is unassigned. But this schedule config does not trigger the pipeline. It simply does nothing, not even show as a pipeline run which does nothing (with all jobs skipped). Seems like the trigger is completely ignored.
This is my workflow file.
---
name: "Organize: Assign Issues + Pull Requests"
on:
issues:
types:
- opened
pull_request:
types:
- opened
schedule:
- cron: '0 9 * * *' # https://crontab.guru/#0_11_*_*_*
permissions:
contents: read
issues: write
pull-requests: write
jobs:
add-to-project:
name: Add to project
runs-on: ubuntu-latest
steps:
- name: Add to project (issues and PRs)
uses: actions/add-to-project#main
with:
project-url: https://github.com/users/sebastian-sommerfeld-io/projects/1
github-token: ${{ secrets.GH_TOKEN_REPO_AND_PROJECT }}
assign-to-user:
name: Assign to user
runs-on: ubuntu-latest
steps:
- name: Assign issue to user when moved into column
uses: pozil/auto-assign-issue#v1
# https://github.com/marketplace/actions/auto-assign-issue
with:
assignees: ${{ github.actor }}
numOfAssignee: 1
allowSelfAssign: true
abortIfPreviousAssignees: true
new-pull-request-chat-message:
runs-on: ubuntu-latest
needs: ['add-to-project', 'assign-to-user']
if: github.event_name == 'pull_request'
steps:
- name: Send message to Google Chat
uses: Co-qn/google-chat-notification#releases/v1
with:
name: New Pull Request "${{ github.event.pull_request.title }}" (raised by ${{ github.actor }})
url: ${{ secrets.GOOGLE_CHAT_WEBHOOK }}
status: ${{ job.status }}
on-failure:
runs-on: ubuntu-latest
needs: ['add-to-project', 'assign-to-user', 'new-pull-request-chat-message']
if: failure()
steps:
- name: Send Pipeline Status to Google Chat
if: always()
uses: Co-qn/google-chat-notification#releases/v1
with:
name: ${{ github.workflow }}
url: ${{ secrets.GOOGLE_CHAT_WEBHOOK }}
status: failure
What bugs me is that the scheduler setting is copied from another workflow where it works just fine. So I cannot think of a reason why this pipeline is not triggered at 09:00 in the morning.

Found a way :-)
I use the Github CLI to get all PRs with a certain label and assign a user. This is a new dedicated pipeline.
---
name: "Organize: Dependabot Pull Requests"
on:
schedule:
- cron: '30 * * * *' # https://crontab.guru
permissions:
contents: read
issues: write
pull-requests: write
jobs:
assign-user:
name: Aassign PRs with label 'dependencies'
runs-on: ubuntu-latest
steps:
- name: Get PR and assign user (filtered by github cli)
env:
GITHUB_TOKEN: ${{ secrets.GH_TOKEN_REPO_AND_PROJECT }}
label: dependencies
assignee: sebastian-sommerfeld-io
run: |
OUTPUT=""
pr_ids="$(gh pr list --repo "$GITHUB_REPOSITORY" --label "$label" --json number --jq '.[].number')"
for id in $pr_ids; do
gh pr edit "$id" --repo "$GITHUB_REPOSITORY" --add-assignee "$assignee"
done
Then I updated the triggers of my original pipeline to
on:
issues:
types:
- opened
pull_request:
types:
- opened
- assigned
