Not able to create item in latest ERPNext

I had used an earlier version of ERPNext and was able to successfully create Item & BOM using the REST API now with the latest that code is not creating the Item and BOM. Did anything changed in the way we create Item & BOM in the latest version.

Can anyone please let me know or point me to the information regarding it?

I am using following version
ERPNext: v11.x.x-develop (0357fbc) (develop)
Frappe Framework: v11.x.x-develop (6acfa8a) (develop)

Thanks in advance.

on item master, some fields has been moved to child table to set company wise defaults. Like Default Warehouse, Default Price List etc.

Can you share exception/error? It helps to identify actual error.
