We're using crx2oak to do blue-green deployments. As a baseline I'm trying the parameter --copy-versions=false to see how much time/space can by gained by excluding versions. However when doing this, in the migrated repository on startup, I consistently get this error:

It surprises me that NOT copying versions causes this. On the other hand, I've seen that copying some versions fixes this problem. I'll continue trying options, but any tips or guidance about what's happening would be very useful.
