Beim Benutzen der GitHub Action alexellis/upload-assets (https://github.com/alexellis/upload-assets) bekam ich folgende Fehlermeldung

Run alexellis/upload-assets@0.3.0
Error: Not Found

Man kann das Problem lösen indem man vorher ein Release erstellt. In meinem Testfall habe ich die GitHub Action actions/create-release@latest (https://github.com/actions/create-release) verwendet. Die gesamte yml-Datei sah in meinem Testfall dann so aus:

name: Upload assets example

on:
  push:
    tags:
      - v*
  
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3

      - name: Run something
        run: |
          echo "$(date)" > release_file

      - name: Create release
        id: create_release
        uses: actions/create-release@latest
        env: 
          GITHUB_TOKEN: ${{ secrets.UPLOAD_TOKEN }}
        with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          draft: false
          prerelease: false
