Additional context

[gempain]

The issue was coming from calls to logger.log in migrate-inventory-items.ts. I changed them to log.info and things worked fine.

I had the same problem. I commented out all the logger_1.default.log(...) code in migrate-inventory-items.js file and the migration went fine 🤷🏼‍♂️
