Do smart contract needs a SFT to call esdt_local_mint

Question

My smart contract owns the SFT HAT-a1a1a1-01.
The SFT HAT-a1a1a1-02 also exists but isn't owned by the SC.

When I add local quantity to the SFT with the 02 nonce through a function, my transaction fails with this error:

new NFT data on sender

Do I need to own the SFT HAT-a1a1a1-02 to mint it?

Answer 1

I got an answer in another group:

Yes, you need to own at least 1 to AddQuantity, since otherwise, you wouldn't have the attributes. When you send an NFT/SFT, if your balance after is 0, the metadata is erased from your account.
