Typescript throws a "Cannot read property 'length' of undefined" when run through gulp
I am trying to build a project in Gulp that uses Typescript. However, when I try to do npm run gulp
, the following error is thrown:
[09:03:17] Using gulpfile ~/Programming/Projects/ghars/gulpfile.js
[09:03:17] Starting 'default'...
[09:03:19] 'default' errored after 2.25 s

I tried putting a console.log
statement in typescript.js
to try to see what files are being processed, but it seems like all of the obvious files were compiled. I'm not sure what I have to do to resolve this error, as I am unfamiliar with Typescript.
Here is my gulpfile.js:
var gulp = require('gulp');
var ts = require('gulp-typescript');
var tsProject = ts.createProject('tsconfig.json');
gulp.task('default', function () {
return tsProject.src()
.pipe(tsProject())
.js.pipe(gulp.dest('dist'));
});
Here is my tsconfig.json:
{
"compilerOptions": {
"outDir": "dist",
"rootDir": "./",
"allowJs": true,
"incremental": true,
"target": "es5",
"removeComments": true,
"resolveJsonModule": true,
"sourceMap": true,
"strict": true,
"strictNullChecks": false
},
"include": [
"server"
]
}
