chown doesn't work

[pyronaur]

Got this error:

[14:47:09] gulp-rsync: zsh:1: no matches found: --usermap=*:www-data --groupmap=*:www-data
[14:47:09] gulp-rsync:  [14:47:09] gulp-rsync: rsync: connection unexpectedly closed (0 bytes received so far) [sender]
[14:47:09] gulp-rsync:  [14:47:09] gulp-rsync: rsync error: error in rsync protocol data stream (code 12) at io.c(226) [sender=3.1.2]

From:
Mac OS X Sierra, rsync 3.1.2

To:
Ubuntu 16.04, rsync 3.1.0

Tried config like this
chown: 'www-data:www-data',
and this:
chown: '"www-data:www-data"',

I'm syncing as root, so I'm fairly certain I have permissions. No idea what do do about this.

That would probably be because, as said here, rsync needs the parameter -og to use --chown.
I was able to make it work enabling the archive option.
Maybe it would be better to add by default the parameter -og if chown is used (and probably -p for chmod).

I found the answer, it's an rsync bug fixed in 3.2.4 or 3.2.5:

I would post this also on ansible/ansible#64971 but unfortunately they use the software engineering anti-pattern of locking issues so they likely will never learn of the answer 😥

Usually adding -s can solve this issue, from rsync manpage:

If you specify "--chown=foo:bar", this is exactly the same as specifying "--usermap=:foo --groupmap=:bar", only easier. If your shell complains about the wildcards, use --protect-args (-s).
