Grails 4.1.0 - "IllegalArgumentException: keyVaultNamespace can not be null" thrown on startup

[ilPittiz]

Upgrading from Grails 4.0.x to 4.1.0, without changing GORM version (7.0.2), an IllegalArgumentException thrown at boot time. The exception is non-blocking, and the web-app starts successfully.

Here's the stacktrace:
