Configuration-as-code-plugin: jobs - stopped working 0.9-alpha -> 0.11-alpha

[jonbrohauge]

Using the cloudbees folder plugin version 6.5.1
This very basic job section breaks in 0.11-alpha:

jenkins:
[...]
unclassified:
[...]
jobs:
  - >
      folder('system') {
        description('system specific jobs are placed here')
      }

The error message is:

BTW: I've tried to use a freestylejob as well with the same error.

source for script has been updated as https://github.com/jenkinsci/configuration-as-code-plugin/commit/0a75f9dda91b52ecfe97cd597553928d793e6811 so it is more flexible. To pass inline script use:

jobs:
  - script: some(groovy).stuff()
