Error in rsync protocol data stream (code 12) when synchronizing with gulp-rsync

When I tried to synchronize files with gulp-rsync, I received the following error:

 gulp-rsync:rsync error: error in rsync protocol data stream (code12)

If it's a simple reason, such as an unstable Internet connection or an incorrect connection destination, I'll report my efforts as I didn't ask this question.
Also, the destination (VPS) is for practice, so the information such as the IP address is included as it is.

import Gulp from "gulp";
importGulpRSync from "gulp-rsync";

Gulp.task(
  "Deploy",
  ( ) : NodeJS.ReadWriteStream=>Gulp.src("03-ProductionBuild/BackEndEntryPoint.js").
      pipe(GulpRSync({
        root: "03-ProductionBuild/",
        hostname: "160.251.43.156",
        port: "22",
        username: "non_root_admin",
        destination: "/var/www/yamatodaiwa.com"
      }))
);

I was told that this could be the cause on the following page.

If asked for the password, try entering the correct password.

The above error occurs.

Message:
    Error: rsync expired with code 12

This time, I will try to enter the wrong password on purpose.
A different error occurs.

non_root_admin @160.251.43.156's password: [18:36:47] gulp-rsync: Permission denied, please try again.

Therefore, the backend side is working properly until authentication.Just in case, I will try connecting to a regular terminal.

It was a success.

rsync-v connected to Terminal VPS and excluded.

The BackEndEntryPoint.js file you are trying to synchronize with code is only 92.0 KB.VPS side disk usage information is as follows:

You must also have the appropriate permissions to create files and folders for synchronization.

[email protected]:/var/www/yamatodaiwa.com that you have specified as your copy destination. In the first place, /var/www is generally not allowed to be written by anyone other than root.

example:

$ls-ld/var/wwww
drwxr-xr-x4 root root 4096 January 25 23:09 / var / www /

If the non_root_admin of the running user is a non-root user, one of the following actions may be taken:

Enable non_root_admin to /var/www
Pre-create /var/www/yamatodaiwa.com so you can write non_root_admin

Or, if the sudo command is allowed on non_root_admin, use the rsync command on the local side to
Using the --rsync-path option may be quick.

If the remote side has non-root permission on rsync, the owner information of the file will not be copied

#rsync--rsync-path="sudorsync"-auvz/path/to/SOURCE ec2-user@REMOTE:/path/to/TARGET
