Hey @jbunce, thanks for opening this issue! The problem here is that you are attempting to scan an umbrella application as a whole. For now, you'll need to scan each Phoenix application individually. Something like mix sobelow -r apps/APP_NAME.

That said, Sobelow shouldn't be throwing such an unhelpful error message. I've pushed an update to master that will appropriately advise users on how to proceed! If you want to try out the master branch, you can install with mix archive.install github nccgroup/sobelow.

Thanks again for opening this issue!
