replace gulp3 "run-sequence" with "gulp-task-error-handler".

• gulp3 run-sequence

const gulp = require('gulp');
const runSequence = require('run-sequence');

gulp.task('package', (cb) => {
  runSequence('tsc-debug', '_rm-package', '_package-debug', '_unpacked', '_notify', '_kill', (err) => {
    if (err) {
      gulp.start('_notifyError');
    }
    cb(err);
  });
});

• replace with "gulp-task-error-handler" sample.

const gulp = require('gulp');
const handler = require('gulp-task-error-handler');

gulp.task('package',
  handler(gulp.series('tsc-debug', '_rm-package', '_package-debug', '_unpacked', '_notify', '_kill'), (err) => {
    gulp.task('_notifyError')();
  })
);
