# Bug with minting ERC721 token in the initial transaction using Smart Contract Wallets

When we are trying to mint an NFT in the first transaction which deploys the wallet also, one of the internal transactions is failing(which is for minting the ERC 721 Token): https://mumbai.polygonscan.com/tx/0x41bfb9790263af99b9c37f0ebb3204ad4dcc8c50ac76112fcc4d5b74ebb8b375

Here is our verified smart contract proxy: https://mumbai.polygonscan.com/address/0x11e07aF8ac20a75727132AD8A3b0803D14fd6f4A#code

Here is the singleton contract: https://mumbai.polygonscan.com/address/0x66D61387800d62695Df91A2018f54Eec3b832a34#code

This transaction is also containing the init code to deploy the wallet. In the above transaction, we can see that the final transaction is failing and every other transaction is getting succeeded.

I think that in the initial transaction, the wallet deployment is not complete and we call the SCW for checking that it is ERC721 compatible using the function

function onERC721Received(
        address,
        address,
        uint256,
        bytes memory
    ) public virtual override returns (bytes4) {
        return this.onERC721Received.selector;
    } 

Our contracts are SAFE smart contract wallets and we are using the latest code from ETH infinitism for Bundler and Entry Point.
