Describe the bug

The following command, run on the default foundry template (forge init) results in the contract being deployed and then subsequently, the verification failing with the following error:

forge script script/Counter.s.sol:CounterScript --broadcast --slow --rpc-url base --verify -vvvv

Submitting verification for [lib/forge-std/src/Base.sol:CommonBase] <address>.
Encountered an error verifying this contract:
Response: `NOTOK`
Details: `Invalid constructor arguments provided. Please verify that they are in ABI-encoded format`

It also fails on optimism (so I think it affects all chains, although it is possible it might only affect op-stack chains).

You will need to add the following to your foundry.toml

[rpc_endpoints]
base = "${BASE_RPC_URL}"
optimism = "${OPTIMISM_RPC_URL}"

[etherscan]
base = { key = "${BASE_ETHERSCAN_API_KEY}", url = "${BASE_ETHERSCAN_VERIFIER_URL}" }
optimism = { key = "${OPTIMISM_ETHERSCAN_API_KEY}", url = "${OPTIMISM_ETHERSCAN_VERIFIER_URL}" }

I then downgraded to this version of foundry from two weeks ago and the deployment + verification works fine. Note that the eip1559 fix wasn't implemented by this time, so make sure you account for that or you will tip 3gwei.
