Thanks for reporting. I just ran a mnt2 migration and it succeeded on my side.
Can you run a migration with the following flags and post the output here?
pv-migrate --log-level debug --log-format json migrate ...
from pv-migrate.

The error "an empty namespace may not be set during creation" confused me, so I tried specifying the destination namespace and succeeded:
-> % pv-migrate --log-level debug --log-format json migrate --dest-namespace migrate data destination

Thanks, it still looks like a bug because normally you should not need to specify the namespace - it should pick the one in the context. I'll have a look into reproducing and fixing it.

Sounds great! Let me know if I can be of any help. I'm happy to test a potential fix.

I believe I understood the cause and my latest commit fixes the issue.
Feel free to test it when I make the next release, or by building the master branch yourself.
