The example from the documentation doesn't work (for me)

[cellularmitosis]

Hi,

I am new to this tool and just tried it for the first time.

I followed the instructions at https://giginet.github.io/Scipio/documentation/scipio/prepare-cache-for-applications/ but it doesn't work. It simply says "invalid package":

$ scipio prepare .
🔁 Resolving Dependencies...
Error: Invalid package. /Users/cell/scipio-demo/MyAppDependencies

I used the Package.swift from the documentation.

Is there any sort of log or trace where I might get more details about why it failed?
