Why doesn't the dest function in gulpfile.js work?

Question

Frontend

there is a function in gulpfile.js that compresses votki

function images(){
    return(src("big_image/**"))
    .pipe(imagemin())
    .pipe(dest("app/image"))
    .pipe(browserSync.stream())
}

when I run it, an error is displayed in the terminal:
TypeError: dest.on is not a function

on all other functions like translating preprocessors in css and so on - they work without problems.
I already played with the specified unloading path, nothing works, the error is the same.

what needs to be fixed?
