Github Actions produces gmp_mod(): Argument #1 ($num1) must be of type GMP|string|int error

[sts-ryan-holton]

When running my Laravel test suite via Github Actions I get the following error:

gmp_mod(): Argument #1 ($num1) must be of type GMP|string|int, Illuminate\Support\Stringable given

Also see my workflow file:

name: tests

  pull_request:
  schedule:
    - cron: '0 0 * * *'

  tests:
    runs-on: ubuntu-22.04

    strategy:
      fail-fast: true
      matrix:
        php: [8.3]

        exclude:
          - php: 8.3
            laravel: 11

        run: |
          if [ ! -f database/database.sqlite ]; then
            touch database/database.sqlite
          fi

      - name: Run migrations
        run: php artisan migrate
        env:
          DB_CONNECTION: sqlite
          DB_DATABASE: database/database.sqlite

      - name: Execute tests
        run: vendor/bin/phpunit
        env:
          DB_CONNECTION: sqlite
          DB_DATABASE: database/database.sqlite

What am I missing? My test calls Hashids like: (new Hashids('', 7))->encode(rand(11111111, 99999999).''.rand(111111, 999999))
