'Allrun' script in vofToLagrangian is not working

The Allrun script doesn't work for this group of folders. The error is:

Error: unable to find Lagrangian data in case ../eulerianInjection/processor0 Restore 0/ from 0.orig/ Error: unable to find Lagrangian data in case ../eulerianInjection/processor0

I also do not understand how this solver actually works, or what it is supposed to do. Is there any better information on it? I'm running this on docker.
