Migration Plugin

I'm on commit 0c7bbf000e55af5ff4c0d9266427476675e409ab of pulp-2to3-migration

I'm creating a migration plan of: {"plan":{"plugins":[{"type":"iso"}]}}
But when i run it, i get an error of:

Looking at postgres logs, i see:

(note the sql was from a different run than the traceback). The weird parts, i didn't request any importer migration, nor did i request anything yum related.
