Hey
The Collaboration Engine Demo seems to be broken:
https://ce-sampler.demo.vaadin.com/
It throws an error not matter what page you try to open:
There was an exception while trying to navigate to 'custom-user-list' with the exception message 'Collaboration Engine doesn't have write permissions for the data directory at '/data'. Collaboration Engine needs to be able to write files into the folder to function. Make sure that the the system user, running the Java environment, has write permissions to the directory.'
