Gulp gives an error when connecting autoprefixer. What's the problem?

Are trying to run. It gives an error. I can not understand what it refers to ?Google did not help.
The code itself
const gulp = require("gulp");
const sass = require("gulp-sass");
const less = require("gulp-less");
const stylus = require("gulp-stylus");
const sourcemaps = require("gulp-sourcemaps");
const autoprefixer = require("gulp-autoprefixer");



//sass
gulp.task('sasS', function() {
 return gulp.src('./scss/*.scss')
.pipe(sourcemaps.init())
.pipe(sass())
.pipe(autoprefixer({
 browsers: ['last 2 versions'],
 cascade: false
}))
.pipe(sourcemaps.write())
.pipe(gulp.dest('./css/'))
});

//less
gulp.task('lesS', function() {
 return gulp.src('./less/*.less')
.pipe(sourcemaps.init())
.pipe(less())
.pipe(autoprefixer({
 browsers: ['last 2 versions'],
 cascade: false
}))
.pipe(sourcemaps.write())
.pipe(gulp.dest('./css/'))
});

//stylus
gulp.task('stylusS', function() {
 return gulp.src('./stylus/*.styl')
.pipe(sourcemaps.init())
.pipe(stylus())
.pipe(autoprefixer({
 browsers: ['last 2 versions'],
 cascade: false
}))
.pipe(sourcemaps.write())
.pipe(gulp.dest('./css/'))
});




gulp.task('default', gulp.parallel('sasS', 'lesS', 'stylusS'));


Error:

Solution
if I am not mistaken when I used version 3 gulp plugin gulp-autoprefixer recommended to clean (move in package.json) property "browsers: ['last 2 versions']," perhaps in 4 it is causing the error. Try to reschedule. Add a screenshot for clarity
