I think you controller action is incomplete or your view folder also.

• If you keep unchanged your controller, you must have a controller folder name in /grails-app/views (ex /views/home/index.gsp)
• Or indicate the view you use in controller action (ex : render view: '/index' or render view: '/home/index')

[dsomehan]

May I ask if the problem can be reproduced by directly opening the project in IDEA

I tried those cases. It results with similar error. When execute 'grails run-app' works fine. The issue happen if you generates war artifact and then running with 'java -jar'.

I don't used IDEA for this example. Just running whit terminal commands.

I've run into a similar issue where the problem only happens on linux in dev mode. Works fine in on a Mac in dev mode. Also works fine once compiled into a war and running in prod mode on linux.
