Bug description

Visiting /admin/cookbook/step/?all= results in a HTTP 500 error. Debug logs from 500 page included in issue.
I am able to list page 1 (of 2) steps, but navigating to page 2, or listing all steps consistently results in a HTTP 500 error. I've used the API endpoint /api/step/ to query for all steps, and can retrieve information for every one via /admin/cookbook/step/${id}/change. I suspect the database to have a bad entry with a missing field, but have been unable to manually determine which one to delete/replace/update the step.
Database is postgres at version 14 also running in docker.
Relevant logs
