'Parsing error: Unterminated string constant while using Smart Contract ABI

I am following the tutorial: https://youtu.be/WZWCzsB1xUE

and the error state occurs at: 50:00

I have checked multiple times using "", yet problem remains unsolved. Help would be appreciated as I am new to JS and ReactJS. The contract is deployed on polygon testnet with Moralis server support and using the Ethereum bolierplate Can anybody point out if any silly mistake?
