Bundling fails due to json parse issue

[moso80]

Hi,

I sometimes get this error when i save a script- or sass-file: Unhandled rejection SyntaxError: Unexpected end of JSON input at JSON.parse (:null:null) at D:\develop\client\src\Web\node_modules\gulp-bundle-assets\lib\results\index.js:110:49 at tryCatcher (D:\develop\client\src\Web\node_modules\bluebird\js\release\util.js:16:23) at Promise._settlePromiseFromHandler (D:\develop\client\src\Web\node_modules\bluebird\js\release\promise.js:502:31) at Promise._settlePromise (D:\develop\client\src\Web\node_modules\bluebird\js\release\promise.js:559:18) at Promise._settlePromise0 (D:\develop\client\src\Web\node_modules\bluebird\js\release\promise.js:604:10) at Promise._settlePromises (D:\developclient\src\Web\node_modules\bluebird\js\release\promise.js:683:18) at Promise._fulfill (D:\develop\client\src\Web\node_modules\bluebird\js\release\promise.js:628:18) at D:\develop\client\src\Web\node_modules\bluebird\js\release\nodeback.js:42:21 at D:\develop\client\src\Web\node_modules\gulp-bundle-assets\node_modules\graceful-fs\graceful-fs.js:78:16 at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:528:3)

I can't find any pattern of when this error accours.

gulp-task: gulp.task('watch', function () { gbundle.watch({ configPath: path.join(__dirname, '/bundle.config.js'), results: { dest: path.join(__dirname, '/bundles/'), pathPrefix: '/bundles/', fileName: 'bundle.result', unprocessedOutputPathPrefix: "/", sortUnprocessedOutput: false }, dest: path.join(__dirname, '/bundles/') }); });

Example of bundle: main: { scripts: [ config.paths.globalScripts ], styles: [ config.paths.baseLessFile, config.paths.baseSassFile, config.paths.cssFiles, "!Styles/admin/*.css" ], options: { uglify: prodLikeEnvs, minCSS: prodLikeEnvs, watch: { styles: config.paths.globalStyles, scripts: config.paths.globalScripts }, maps: false, result: { type: { scripts: scriptResult } }, transforms: { styles: styleTransforms }, rev: prodLikeEnvs } }

Any idea whats causing this?
