Failed to get recent blockhash, method not found: Connection.getRecentBlockhash

i am creating a NextJs NFT minting App using the React solana wallet adaptor, web3.js, metaplex and umi.

I was trying to upload the offchain metadata and keep getting the error that the getRecentBlockhash method is not found. I think this has to do with web3.js using the method. How can i replace this method with something else that might fix the problem? Thanks!
