I am trying to upgrade magento version from 2.1.8 EE to magento version 2.3.1. I am trying to update using command line procedure given here

https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html

At the step of Modify the Magento updater

I am getting the following error - [InvalidArgumentException]
Could not find package magento/project-enterprise-edition with version 2.3.
0.

enter image description here

I also tried to upgrade through script. It successfully upgraded from magento 2.1.8 EE to magento 2.3.1 EE through script on local setup , but not upgrading on server . The command to run the script just terminates showing no error on server instance.
