engine scss-lint failed because of folder with subfolders

This is how I run codeclimate.

$ docker run -it --rm --env CODECLIMATE_CODE="/code" -v "$PWD":/code -v /var/run/docker.sock:/var/run/docker.sock -v /tmp/cc:/tmp/cc codeclimate/codeclimate analyze

And thats the result.

Starting analysis
Running structure: Done!
Running duplication: Done!
Running csslint: Done!
Running scss-lint: Done!

Thats the .scss-lint.yml.

scss_files: '**/*.scss'

exclude: '**/node_modules'

linters:
  BorderZero:
    enabled: false

  Indentation:
    severity: warning
    width: 2

And here the .codeclimate.yml.

---
version: "2"
plugins:
  csslint:
    enabled: true
  scss-lint:
    enabled: true
  duplication:
    enabled: true
    config:
      languages:
      - javascript
      - typescript
  fixme:
    enabled: true
  tslint:
    enabled: true
    config: tslint.json
exclude_patterns:
- .idea/
- .vscode/
- dist/
- features/
- "**/node_modules/"
- "**/spec/"
- "**/*.d.ts"
- "**/*.spec.ts"

And thats how my project looks like. (small tree)
