The final production build of the UI should have a unminified/uncompressed theme configuration file that resides at config/ThemeConfiguration.js.
Steps to Reproduce
- Check the XUI directory of an AM production deployment.
A config directory exists, with ThemeConfiguration within it.
No directory or file exist.
Modify the UI source directly and perform a build.
The Webpack build is/was configured to not bundle the ThemeConfiguration file with the rest of the assets. That configuration must have either changed to the configuration is no longer valid.
