The package alias is empty. The default package alias will be used instead.

Erroneous example

{
  "is-main": true,
  "import": [
    {
      "path": "username/hello/lib",
      "alias": "" // Warning: The package alias is empty. The default package alias will be used instead.
    }
  ]
}

Suggestion

Use a non-empty alias for the package:

{
  "is-main": true,
  "import": [
    {
      "path": "username/hello/lib",
      "alias": "hello"
    }
  ]
}
