I am trying to fetch a random Jito tip accounts using this code
async function getTipAccount() { const BLOCK_ENGINE_URL = "https://frankfurt.mainnet.block-engine.jito.wtf"; const searcher = searcherClient(BLOCK_ENGINE_URL, signer); const tipAccounts = await searcher.getTipAccounts(); // return a random tip account let randomIndex = Math.random() * (tipAccounts.length - 1) + 1; return new PublicKey(tipAccounts[randomIndex]);}getTipAccount().then().catch(console.error);But I am getting this error below
