Hi @bbg ,
Even if you haven't added libraries manually, tools like dbx can include dependencies from your project setup, which can trigger this error. Try removing all libraries and environment settings from your job, cluster, and task configs before deploying again.
Also, just to note - dbx is deprecated. It's been replaced by Databricks Asset Bundles, which work better with features like for_each_task. If possible, consider switching to Bundles for smoother deployment.
