Coordinator Integration tests - fix account generation to handle and retry on "Replacement transaction underpriced" error

[jpnovais]

Impact

environment: CI Pipeline

Describe the bug

Steps to Reproduce

Coordinator integration tests generate new accounts for every run for test isolation, this account generation relies on whale accounts from the genesis file to fund the new account.

When tests run in parallel, sometimes the same whale account is used to fund the new account and we get Response.Error(code=-32000, message=Replacement transaction underpriced) in net.consensys.zkevm.ethereum.WhaleBasedAccountManager.generateAccounts(AccountManager.kt:149)

The WhaleBasedAccountManager shall be adapted to handle this error and retry funding the account with new nonce

The bugs is not deterministically reproducible. It happens randomly sometimes

Hi, I’d like to work on this issue as a first-time contributor—could you confirm if it’s available and share any guidelines?

Hi, yes issues is still open to be addressed. As mentioned in the ticket description the error shall be handled here

I would recommend to create a function fundAccount(fromAccountTxManager, toAccountAddress, amount) with this code and retries when it gets a "Replacement transaction underpriced" error
