I'm trying to automate uploading my app to testflight using CI/CD on GitLab. I've set up the app store connect variables and set up fastlane and i'm getting No matching runner available even though I've tried using "macos" or "saas-macos-large-m2pro" the runner

My .gitlab-ci.yml looks like this:

stages:
  - debug
  - build
  - deploy

before_script:
  - cd PhoneCall
  - gem install bundler
  - bundle install

build_ios:
  stage: build
  tags:
    - saas-macos-large-m2pro  # Match the instance runner's tag
  image: macos-14-xcode-15
  script:
    - fastlane beta
  only:
    - main  # or the branch you use for releases
