In ERPNext v16.25.0, an error occurs when creating multiple multi-specification items on the Item page.

Information about bug

I installed erpnext v16.25.0 in Docker. Creating a multi-specification item on the item page works normally, but when creating multiple multi-specification items, an error occurs. Can someone tell me how to solve this problem? Additionally, I suggest adding a multi-select button when selecting attributes for creating multi-specification items.

There is a record in the RQ background job as follows，

Job name: erpnext.controllers.item_variant.create_multiple_variants

Arguments:

{ "event": null, "is_async": true, "job_name": "erpnext.controllers.item_variant.create_multiple_variants", "kwargs": { "args": "{"\u5927\u5c0f":["41","42","43","44","45"],"\u989c\u8272":["BLK","COF"]}", "item": "101001", "use_template_image": false }, "method": "erpnext.controllers.item_variant.create_multiple_variants", "site": "erp.pa13.net", "user": "Administrator" }

Job status: Failed
