TypeError в то время как gulp typescript

Я получаю следующую ошибку при выполнении транспиляции Typescript:

TypeError: file.isSymbolic is not a function

моя задача глотка выглядит так:

gulp.task('tsc', function () {
    let tsResult =  gulp.src(srcPaths.tsFiles)
        .pipe(tsProject()); // tsProject created previously

    return tsResult.js
       .pipe(gulp.dest(buildPath)); // -> the gulp.dest(..) command causes the error
});

}

версия узла: 8.9.3 & npm версия: 5.6.0

У кого-нибудь есть идея, что делать?
