Unable to verify contract

[wee4050]

When I used the program to deploy the contract, I also checked that the API was correct, but the contract could not be verified, and the following error occurred.

I has the same issue , I just ran the command "yarn deploy --network truffle" again . This gave me a new contract adress and then I ran the verification with this new adress and it worked fine .

Have a nice day adn I hope this helps
