Using Neos & Flow Installation & Deployment

Hi everyone!

I tried to use language dimensions and set german as the default language.
Unfortunately, I get the following error when i run the migration:

root@8d4374ef49b0:/var/www/html/Neos# ./flow node:migrate 20150716212459

uriSegment: ‘’
en:
label: English
values:

uriSegment: ‘en’

Any ideas?
