Generate causing 'ModuleRootManager.getInstance must not be null'

[hemmenm]

IC config page when I click 'Generate' I'm seeing an Error dialog pop-up with the following:

java.lang.IllegalArgumentException: Argument 0 for @NotNull parameter of com/intellij/openapi/roots/ModuleRootManager.getInstance must not be null

Argument 0 for @NotNull parameter of com/intellij/openapi/roots/ModuleRootManager.getInstance must not be null
