Advanced Usage in Phoenix.View no longer works

Following the readme and adding ExCSSModules to the phoenix view block returns the following error:

Any idea how to fix it?

Sorry for not answering earlier, I totally missed your message :(

The error alone does not reveal to me what is going wrong. Could you share your implementation?
You could also check out this (rather old) example repo as a working example: https://github.com/DefactoSoftware/cells_and_modules
