Yes, the errors are still there with v3.x. I even deleted the build/ and node_modules/ directories because I thought there might be outdated files in there. But that didn't help. However, since the MongoDB schema upgrades were successful during the ./nodebb upgrade runs, I was able to complete the upgrade by doing a fresh git install and copying back the old config.json before running the setup routine. I then manually restored all the static files in public/uploads via rsync.
