In the process of developing the ethereum dapp, I tested the load and there was a nonce error.
When building a rawTx, I used web3.getTransactionCount("accountAddress", 'pending') as the nonce of the transaction.
I didn't think there was going to be a nonce error, because I didn't use web3.getTransactionCount("accountAddress") as the nonce of the transaction, but it happened.
I wonder how to handle it.
