body: <p>I'm following the tutorial here: <a href="https://chainstack.com/how-to-create-blockchain-bridge/" rel="nofollow noreferrer">https://chainstack.com/how-to-create-blockchain-bridge/</a> and getting stuck (seeing nothing) at line 34 in <a href="https://github.com/chainstack/blockchain-bridge-simplified/blob/master/backend/contract-methods.js" rel="nofollow noreferrer">contract-methods.js</a> and if I set timeouts, I get a timeout.</p>
  <p>Here's the repo for it: <a href="https://github.com/chainstack/blockchain-bridge-simplified" rel="nofollow noreferrer">https://github.com/chainstack/blockchain-bridge-simplified</a></p>
  <p>What is the issue?</p>
