AttributeError in Item Table

ERPNext
1

ERPNext: v14.68.2

I try to change the length of item_code lower then I got this error below. If the change is higher, the system will accept.

AttributeError: ‘CustomizeForm’ object has no attribute ‘check_length_for_fieldtypes’

Is this a normal behavior, then how to override?

Please open the console log by pressing F12 and examine the error line.

I think the error originates from this file because the validation is set in the mentioned file. Please check it accordingly.

Is there another way to limit the length of value of the field i.e. item_code.
