If you get that, it means webpack failed.
The confusing error is because the stats data structure of our webpack (4.30.0) is not compatible with the webpack they expect (2.7.0).

To actually see the errors, tweak the compiler.run callback like this:

compiler.run((err, stats) => {
  var stringify = require('json-stringify-safe');
  console.log(stringify(stats, null, 2));
});

I attach the JSON it prints. Sample extract:

"error": {
  "origin": null,
  "dependencies": null,
  "module": "[Circular ~.compilation.entries.0]",
  "name": "ModuleBuildError",
  "error": {
    "code": "BABEL_VERSION_UNSUPPORTED",
    "version": "6.26.0",
    "range": "^7.0.0-0"
  }
}
