Resolved Plesk preview upgrade error

[Hways]

Hello
I am trying to upgrade to the preview version from the current one via SSH on Centos 7.4

When I run
sh <(curl https://autoinstall.plesk.com/one-click-installer || wget -O - https://autoinstall.plesk.com/one-click-installer) --tier testing

I get the error
Cannot write to "-" Broken pipe

I have no idea why.
I ran the SSH as root.

Thank you
