How to remove (or at least localize) the error Error: ENOENT: no such file or directory `some_file_name.ts___jb_tmp___`?

Question

npm

Problem: in the current project, when watchers are running, in 50% of cases, changing files throws an error:

ENOENT: no such file or directory, stat '/home/username/PhpstormProjects/js/bd/src/ts/classes/bd/file_name.ts___jb_tmp___'
at Error (native)

What is this postfix `___jb_tmp___` I have no idea. Google doesn't find anything. Search by node_modules - too.
How to determine in general - in the direction of which plugin to dig?

JS task in gulp:

gulp.task('js', function() {
   gulp.src('src/ts/bd.ts')
       .pipe(plumber())
       .pipe(sourcemaps.init())
       .pipe(webpack({

Watchers and server in Gulp

var config = {
    server: {
        baseDir: "./dist"
    },
    host: 'localhost',
    port: 9005,
    ui: {
        port: 8080,
        weinre: {
            port: 9090
        }
    },
    logPrefix: "prefix"
};

gulp.task('watch', function(){
    watch('src/ts/**/**', function(event, cb) {
        gulp.start('js');
    });
    watch('src/*.html', function(event, cb) {
        gulp.start('html');
    });
});

gulp.task('webserver', function () {
    browserSync(config);
});

Answer 1

jb_tmp, this is obviously a JetBrains temp file :) And the problem is that your watcher is trying to watch all the files:
Correct the path to 'src/ts/**/*.ts', it should help.
