It turns out that it’s due to the migratepassword plugin as discussed here:

Looks like it’s triggering a bug in the migratepassword plugin. It works in my tests, so I’m not sure what’s happening here. I suggest you disable the plugin during the migration. It’s not needed during the migration anyway.
