Gulp lastRun always gives undefined, how to fix?

Question

gulp.js

Actually, I write the following code:

gulp.task('assets', function() {
  
  return gulp.src(sourceDir, {since: gulp.lastRun('assets'), base: repoDir}) 
  .pipe(gulp.dest(publicDir))
})

gulp.lastRun - always returns undefined. I read the forums - they write there that there was a bug, it was closed. I have the latest version of that package, taking into account those fixes.
I tried to look at other tasks - in all lastRun undefined :(

Проблема в том, что Вы пытаетесь использовать фичу, которая доступна только начиная с новой версии GULP 4.
Обновите галп, и проблема исчезнет!
