Creating multiple variants fails sometimes with ValidationError: Item Code is mandatory because Item is not automatically numbered

Hi all,

we have a strange symptom when trying to create mutliple variants from an item template. The template exists and already has other variants. The background job is started, but fails with

Traceback (most recent call last):
  File "/home/frappe/frappe-bench/apps/frappe/frappe/utils/background_jobs.py", line 97, in execute_job
    method(**kwargs)

ValidationError: Item Code is mandatory because Item is not automatically numbered

Interesting is that when the same is tried again, it works and creates the variants.

The version is

ERPNext: v10.1.38 (master)
Frappe Framework: v10.1.36 (master)

Does anyone else have the same issue? Any insights?
