Ios 克隆证书repo时出错，请确保您具有要使用的存储库的读取权限

我正在使用fastflane处理CI，这是我的

Fastfile

：

default_platform(:ios)

platform :ios do
  desc "Push a new beta build to TestFlight"
  lane :beta do
    if is_ci
      create_keychain(
        name: ENV['MATCH_KEYCHAIN_NAME'],
        password: ENV["MATCH_KEYCHAIN_PASSWORD"],
        default_keychain: true,
        unlock: true,
        timeout: 3600,
        lock_when_sleeps: false
      )
    end

    match(
      type: "appstore",
      readonly: is_ci,
      keychain_name: ENV['MATCH_KEYCHAIN_NAME'],
      keychain_password: ENV["MATCH_KEYCHAIN_PASSWORD"]
    )

    build_app(
        workspace: "Runner.xcworkspace",
        scheme: "Runner",
        export_method: "app-store"
    )

    upload_to_testflight
  end
end

但当我在Github操作中执行脚本时：

- name: Setup SSH Keys and known_hosts for fastlane match
      run: |
        SSH_PATH="$HOME/.ssh"
        mkdir -p "$SSH_PATH"
        touch "$SSH_PATH/known_hosts"
        echo "$PRIVATE_KEY" > "$SSH_PATH/id_rsa"
        chmod 700 "$SSH_PATH"
        ssh-keyscan github.com >> ~/.ssh/known_hosts
        chmod 600 "$SSH_PATH/known_hosts"
        chmod 600 "$SSH_PATH/id_rsa"
        eval $(ssh-agent)
        ssh-add "$SSH_PATH/id_rsa"
      env:
        PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
    - name: Deploy to TestFlight
      run: |
        cd ./ios && bundle exec fastlane beta
      env:
        TEAM_ID: ${{ secrets.TEAM_ID }}
        ITC_TEAM_ID: ${{ secrets.ITC_TEAM_ID }}
        FASTLANE_USER: ${{ secrets.FASTLANE_USER }}
        FASTLANE_PASSWORD: ${{ secrets.FASTLANE_PASSWORD }}
        FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD: ${{ secrets.FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD }}
        FASTLANE_SESSION: ${{ secrets.FASTLANE_SESSION }}
        MATCH_PASSWORD: ${{ secrets.MATCH_PASSWORD }}
        MATCH_KEYCHAIN_NAME: ${{ secrets.MATCH_KEYCHAIN_NAME }}
        MATCH_KEYCHAIN_PASSWORD: ${{ secrets.MATCH_KEYCHAIN_PASSWORD }}
        DELIVER_ITMSTRANSPORTER_ADDITIONAL_UPLOAD_PARAMETERS: ${{ secrets.DELIVER_ITMSTRANSPORTER_ADDITIONAL_UPLOAD_PARAMETERS }}

告诉我：
