Why am I seeing this error:

```auto
TypeError: Error loading "testDist/bundles/test/index" at http://localhost:8080/testDist/bundles/test/index.js
testDist/bundles/test/index detected as System.register but didn't execute.

```

when generating index.js using steal build using this config via grunt task:

```json
{
        "options": {
          "steal": {
            "main": "test/index",
            "config": __dirname + "/package.json!npm"
          },
          "buildOptions": {
            "dest": "testDist",
            "minify": false,
            "bundleSteal": true
          }
        }
      }

```

and package.json as

```json
"steal": {
    "plugins": [
      "steal-stache",
      "steal-less"
    ]
  }

```
