Error management at contract deployment

[iboxgithub]

Hi,

what would be the best way to catch errors during contract deployment here? a Try Catch or something else?
Because when I send too many transactions at the same time I have errors like already known or replacement fee too low that make my code bug so I would like to capture them to have proper error management (and no code crash)

  const factory = new ethers.ContractFactory(_metadata.abi, _metadata.data.bytecode.object, _signer)
  const contract = await factory.deploy(..._args) 
  console.log(`deploying contract at [${contract.address}]`)
  // ---> crashes happen from here most of the time
  await contract.deployed()
  console.log(`contract deployed`)
  return contract.address

If you are going to flood the network with several transactions faster than your backend updates the pending transaction count, you can use the NonceManager to serialized them.

Hi thanks, will give it a try, so 2 points:

• isn't this similar to what Alchemy Transact is trying to do? (basically managing the state of a tx for us)
• it still doesn't show me how to catch the error though, would you have a code snippet to share/recommend for that?
