node.js - VSTS Gulp build step error -

i have issue while setting build steps in vsts. use gulp generate css less files. in visual studio (task runner explorer) works fine, following build error when it's run in vsts:

gulp failed error: c:\npm\modules\gulp.cmd failed return code: 1

i tried example mentioned in the docs npm / gulp setup, didn't work me either. change applied setting path gulpfile.js. left rest untouched (npm install arguments, gulp task name, working folders, etc.) yet got error mentioned above.

any suggestions doing wrong?

here's full log of failing build step:
