GST category is not getting updated if the order is placed from international address to indian address

Hi Team,
Here is one case, if the person has an international address, and places a new order for the Indian address, then a new address is created but the GST category for the newly address created address is not getting updated, It remains over cease and the order is not getting synced with Erpnext and throws error message **"Cannot set GST Category as overseas for Indian Address"**.


Expectation -
If the person has an international address and places a new order for the Indian address, The GST category has to be changed from over cease to registered or unregistered for the newly created Customer, and the order has to get synced with Erpnext.

Thanks & regards
Anoop

Start by reproducing the international-to-Indian address order flow described in the issue and trace the Python integration path that creates or updates the customer address. Verify how the GST category is assigned and confirm done when the new Indian address receives a valid category and the order syncs with ERPNext without the overseas-address error.
