Error message does not say much (and how to enable stack trace?)

[binarykitchen]

A recent run of our gulp-compass task failed on our CentOS build server:

{ [Error: Compass failed]
  message: 'Compass failed',
  fileName: '/home/buildagent/workspace/xxx/assets/theming/yyy.scss',
  showStack: false,
  showProperties: true,
  plugin: 'gulp-compass',
  __safety: { toString: [Function] } }

It doesn't say much, why, what and where the error is coming from. How can we set showStack to true?

We are using gulp-compass v2.0.3 here and on the build server we have these gems installed:

compass (1.0.1, 0.12.1)
compass-core (1.0.1)
compass-import-once (1.0.5)

our gulp task is:

gulp.task('theming', ['theming:static'], ->
  gulp.src("assets/theming/**/brands/#{config.brand}/*.scss")
    .pipe(compass(
      debug:       config.debug
      logging:     config.debug
      comments:    not config.sass.compress
      sourcemap:   config.sass.sourcemaps
      style:       config.sass.style
      sass:        'assets/theming/brands'
      css:         "#{paths.public}/brands"
      image:       "#{paths.public}/images"
      font:        "#{paths.public}/fonts"
      import_path: path.resolve('assets/theming')
      config_file: compassConfig(
        """
        generated_images_dir = "#{paths.public}/images"
        asset_cache_buster { "v=#{version}" }
        """
      )
    ))
    .on('error', console.error.bind(console))
    .pipe(tap(logFile))
)

any clues?

Config debug mode and then you can find the compss command. Copy command and paste to your terminal.
