Have you ensured that all of these are up to date?

• Foundry
• Foundryup

What version of Foundry are you on?

forge 0.2.0 (6179312 2024-06-10T00:18:46.177980000Z)

What command(s) is the bug in?

cast send

Operating System

macOS (Apple Silicon)

Describe the bug

I'm trying to send a simple transfer with the following command

cast s --private-key <<PRIV_KEY>> --rpc-url https://rpc.chiado.gnosis.gateway.fm --value 0.1ether <<ADDRESS>> "0x"

I also tried

cast s --private-key <<PRIV_KEY>> --rpc-url https://rpc.chiado.gnosis.gateway.fm --value 0.1ether <<ADDRESS>>

The server returns

Error:
server returned an error response: error code -32602: too many arguments, want at most 1

It most likely fails on eth_estimateGas, since when I specify --gas-limit it works fine. I also tried connecting to a local RPC where I have access to the logs to and I saw that estimateGas is called multiple times.

I downgraded foundry to find the first release where the error pops up. It's https://github.com/foundry-rs/foundry/releases/tag/nightly-cafc2606a2187a42b236df4aa65f4e8cdfcea970

This seems to be related to Chiado testnet. On gnosis chain and arbitrum it works fine. Will test more networks

could you share the logs RUST_LOG=trace cast...

too many arguments is weird, perhaps it's the state override argthat's not included, so it can only be the BlockId argument, perhaps an issue with chiado?

we're def sending a valid request:

�{"method":"eth_estimateGas","params":[{"from":"0xc34b4858cf5f89916559fab2f864384d74b2f996","to":"0xc34b4858cf5f89916559fab2f864384d74b2f996","maxFeePerGas":"0xb368f487","maxPriorityFeePerGas":"0xb368f479","value":"0x38d7ea4c68000","input":"0x","chainId":"0x27d8"},"latest"],"id":2,"jsonrpc":"2.0"}

so it looks like the eth_estimateGas endpoint doesn't fully support the spec?

cast rpc web3_clientVersion --rpc-url "https://rpc.chiado.gnosis.gateway.fm/"
"erigon/2.60.1/linux-amd64/go1.21.5"

Thanks for digging into it. I will get in touch with the Erigon team.
So far I can confirm that it only occurred on Erigon clients. However, what bothers me, is that older foundry versions are compatible (as I mentioned April 24 and older)

Edit: I tried with Geth and Nethermind RPCs on Chiado and it always worked. Seems to be related to Erigon.

Erigon v2.60.1 has a breaking change that removes the 2nd argument from eth_estimateGas. See erigontech/erigon#10495

[yperbasis]

The breaking change was reverted in Erigon v2.60.2.

we also fixed this on the client side and exclude the argument if missing
