I’m trying to merge 2 repository into a third one with the help of GitHub Actions. Note that the 3 repositories are private.

I tried to do it using secrets, but when I try to merge from the third repository, it cannot find any of the two other. Here is the workflows of the repositories:

Any of the first two:

name: Push to Third repo

on:
  push:
    branches:
      - main

jobs:
  trigger:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Trigger the third repository
        run: |
          curl -X POST 
          -H "Authorization: token ${{ secrets.MY_SECRET_TOKEN }}" 
          -H "Accept: application/vnd.github.v3+json" 
          https://api.github.com/repos/MyOrganisation/ThirdRepo/dispatches 
          -d '{"event_type": "event_name_first"}'

And for the third one:

name: Merge Changes to Third

on:
  repository_dispatch:
    types: 
      - event_name_first
      - event_name_second

jobs:
  merge:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repository
        uses: actions/checkout@v2

      - name: Configure git
        run: |
          git config --global user.name "github-actions"
          git config --global user.email "[email protected]"

      - name: Add remote repository
        run: |
          git remote add first https://github.com/MyOrganisation/first.git
          git remote add second https://github.com/MyOrganisation/second.git

      - name: Fetch latest changes from first or second
        run: |
          if [[ "${{ github.event.action }}" == "event_name_first" ]]; then
            git fetch first main
            git merge first/main --no-edit
          elif [[ "${{ github.event.action }}" == "event_name_second" ]]; then
            git fetch second main
            git merge second/main --no-edit
          fi

      - name: Push to main
        run: |
          git push origin main

An this is the error:

remote: Repository not found.
fatal: repository 'https://github.com/MyOrganisation/first.git/' not found
Error: Process completed with exit code 128.

I am sure of the names of every url. I suspect a missing permission on the secret token, even thought I gave it all repo and workflow rights.
