How to deploy install of MS SQL Server 2017 Developer Edition via command-line script - not working
In the error is states the reason which seems fairly self-explanatory:


  You have selected a feature that is not supported for Windows Server Core... [Features Supported]


One of your input arguments is SQL which translates into:


SQL Engine
Replication
Fulltext
DQ
Polybase
Advanced Analytics (R)
R Packages


Instead of putting SQL in the features list, only put what you need. If what you need isn't supported on Windows Core, then don't install on Windows core.
