Failed github workflow updating from strauss 0.17.0

Hi,

composer.json :

{
    "require": {
      "aws/aws-sdk-php": "^3.317",
      "brianhenryie/strauss": "^0.19.2"
    },
    "extra": {
      "aws/aws-sdk-php": [
        "CloudFront"
      ],
      "strauss": {
        "target_directory": "deps",
        "namespace_prefix": "TESt\\CdnPurge\\",
        "classmap_prefix": "TESt_CdnPurge",
        "constant_prefix": "CDN_PURGE_",
        "delete_vendor_packages": true
      }
    }
}

I have this github workflow ci.yml :

name: ci-pipeline

on: ["pull_request"]

jobs:
  build:
    runs-on: ubuntu-latest

    services:
      mysql:
        image: mysql:latest

          MYSQL_ROOT_PASSWORD:
        ports:
          - 
        options: >-
          --health-cmd="mysqladmin ping"
          --health-interval=10s
          --health-timeout=5s
          --health-retries=3

    strategy:

          composer install --prefer-dist --no-progress
          npm ci --prefer-offline --progress=false
          cd libraries
          composer install --prefer-dist --no-progress
      - name: Test php
        run: bash bin/install-wp-tests.sh wordpress_test root password 127.0.0.1 $WP_VERSION
        env:

          composer check-php
          npm run lintjs -- --no-error-on-unmatched-pattern
          npm run lintcss -- --allow-empty-input

If I use any strauss version above 0.17.0 I have this error in the "Install dependencies" section:
