New Resource throws "is an empty directory" exception in Forge deploy

Hi everybody,

I´m adding a new resource to my manifest.yml, when deploying the Forge App I´m getting following error:

Error: Resource admin_approval_page at: C:\Users\my-user\Development\my-app\src\frontend\admin_page\approval.jsx is an empty directory

There is no directory in file system with this name, also files exists and using an existing one from a resource which works brings the same error.

My manifest.yml looks like that, when removing the new entry deployment works without any errors.

resources:
  - key: admin_config_page
    path: src/frontend/admin_page/global_config.jsx
  - key: admin_approval_page
    path: src/frontend/admin_page/approval.jsx
  - key: issue_panel
    path: src/frontend/issue/panel.jsx
  - key: issue_activity
    path: src/frontend/issue/activity.jsx

All components are up-to-date, downgrading to previous LTS shows the same error.

New resource should be used as page in App Admin.
