Staking Transaction Error

[adam-young-dev]

Summary

I create and submit a simple staking transaction but get an error

Registering stake certificate transaction goes through successfully
But delegating stake certificate transaction get back the error

Did a similar staking transaction with Lucid, goes through successfully

Steps to reproduce the bug

Here is the code:

const blockchainProvider = new BlockfrostProvider('preprodKaL…ECp');

const wallet = new MeshWallet({
  networkId: 0, 
  fetcher: blockchainProvider,
  submitter: blockchainProvider,
  key: {
    type: 'mnemonic',
    words: ‘…’,
  },
});

async function delegate() {
  const addresses = await wallet.getRewardAddresses();
  const rewardAddress = addresses[0];
  const poolID = "pool1y74f44yeedrls4nj0yf6h5pdl5ythd5ahm73knqf33hfvq9rhaf"
  const tx = new Transaction({ initiator: wallet })
    .delegateStake(rewardAddress, poolID);

  const unsignedTx = await tx.build();
  const signedTx = await wallet.signTx(unsignedTx)
  const txHash = await wallet.submitTx(signedTx);
  console.log("txHash: ",txHash)
}

Actual Result

Get an error:
