Error: Max fee less than base fee sometimes when deploying to alternative L1/L2 for rootchain

Max fee less than base fee sometimes when deploying to alternative L1/L2 for rootchain

Description

If you're deploying to an alternative rootchain, such as Ethereum or Goerli, regardless of RPC used, the stake-manager-deploy and rootchain deploy command intermittently fails depending on network activity and gas fees. This issue occurs with an error along the lines of max fee per gas less than block base fee: address 0x5FFF686fF9dA3f66F6EC1C58Dd2C266390B6e53A, maxFeePerGas: 1496959907 baseFee: 1621120078 (supplied gas 15010499)

Your environment

Ubuntu
Polygon Edge tag v1.0.1
Cloud hosted (Using supernets terraform deployment)

Steps to reproduce

Run the https://github.com/maticnetwork/terraform-polygon-supernets deployment, but target Goerli Eth instead of the deployed geth instance.

Expected behavior

Rootchain contracts should deploy without issue, and occasionally without any other configuration changes they do - this seems to be dependent on the rootchain network gas/gwei price and network activity overall. When there's low to no network activity and fees are low, there's no issues.

Proposed solution

Fix plz

[iamarkdev]

Just tried the same on Sepolia, same exact problem. err: max fee per gas less than block base fee: address 0x5FFF686fF9dA3f66F6EC1C58Dd2C266390B6e53A, maxFeePerGas: 164983 baseFee: 174243 (supplied gas 15010499)\"}

For further context, here is my bootstrap script I'm using with terraform-polygon-supernets.

#!/bin/bash -x

#
# NOTES:
# 1. deployer addr must be prefunded with stake token on rootchain

This is fixed in #1718, which is going to be included in the next release, which is expected in the following days.
