I'm trying to call the connection.getLatestBlockhash(...) method in @solana/web3.js (version 1.50.1) on localnet but I keep encountering
Error: failed to get recent blockhash: Error: failed to get latest blockhash: Method not found
Is anyone else encountering this issue? Is this method unavailable on localnet? If it's just a problem with my local network, any known solutions?
The getLatestBlockhash function is new in Solana version 1.9, see here: https://docs.solana.com/developing/clients/jsonrpc-api#getlatestblockhash
NEW: This method is only available in solana-core v1.9 or newer. Please use getRecentBlockhash for solana-core v1.8
Are you on an earlier version by any chance? If you run solana-test-validator --version it'll tell you which version you have.
If you do have an earlier version you should be able to install the latest with solana-install update.
