Problem with Mint

Hello first thank you for sharing the Free smart contract with us I use your Reveal Smart contract and that works fine for me before now I have an unknown issue, sir, I deploy the contract and if I try to test it using a mint page from another wallet to mint in Rinkeby I receive this error: https://prnt.sc/nKOmLJ7fu5Wj


Can you please help me to fix it , and thank you very much
