hello everyone i have a problem with minting transactions on Ethereum network every time it fail .i can't change the contract so hope we can find out how to solve it from the dapp .
note: direct mint from smart contract is working fine
contract CRYPTOCGS1 is ERC721Enumerable, Ownable {

i found the solution for this problem is by editing the app.js file
line 133 you need to replace
.mint(blockchain.account, mintAmount)
with
.mint(mintAmount)
