Component

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

Foundry
Foundryup

What version of Foundry are you on?

forge 0.2.0 (73fb616 2023-12-19T00:16:21.131413571Z)

What command(s) is the bug in?

forge test --fork-url $SEPOLIA_RPC_URL

Operating System

Linux

Describe the bug

i found #3621 which is very similar to my issue to be closed in lieu of #6079, so i apologize if this is dup issue,

there is nothing special about my test, and everything passes and completes without issues. unlike @amusingaxl however, trace shows no problems with rate limiting, traces all look pretty standard:

2023-12-21T23:26:59.714575Z  WARN etherscanidentifier: could not get etherscan info: Serde(Error("expected value", line: 1, column: 1))

i am working on a remote server thru vscode remote ssh, not sure if that's a factor

The text was updated successfully, but these errors were encountered:

slordua · 2023-12-22T03:03:32Z

btw this is caused by this entry in foundry.toml

[etherscan]
sepolia = { key = "${ETHERSCAN_KEY}" }

don't have this issue when omitted

don't think anything is wrong with my config because there's no issue verifying contracts elsewhere

mattsse · 2023-12-22T09:04:14Z

mind sharing the etherscan api url?
this is either wrong API or a JS challenge for some reason, which doesn't really make sense for API URLs... but etherscan has these

slordua · 2023-12-22T20:22:12Z

direct copy and paste

[rpc_endpoints]
mainnet = "${MAINNET_RPC_URL}"
sepolia = "${SEPOLIA_RPC_URL}"

[etherscan]
mainnet = { key = "${ETHERSCAN_API_KEY}", url = "https://api.etherscan.io/api" }
sepolia = { key = "${ETHERSCAN_API_KEY}", url = "https://api-sepolia.etherscan.io/api" }

and .env

MAINNET_RPC_URL="http://127.0.0.1:8545"
SEPOLIA_RPC_URL="http://127.0.0.1:8546"
ETHERSCAN_API_KEY="RR2Q7D9SP4ATYZENACMCSWC5QPXTTVH318"

if i use url = "https://api.sepolia.etherscan.io/api" i actually don't get the error, but this can't be correct right? additionally, it's not getting any of the traces it should when i remove all my vm.labels (that was my workaround)

rocketman-21 · 2023-12-23T00:49:08Z

--verifier etherscan --verifier-url https://api-sepolia.etherscan.io/api\? adding to the end of my commands helped w/a similar issue

slordua · 2023-12-23T03:25:28Z

tried passing that but i get invalid escape sequence

2023-12-21T23:26:59.714575Z  WARN etherscanidentifier: could not get etherscan info: Serde(Error("expected value", line: 1, column: 1))

and

ERROR etherscan: Failed to deserialize response: expected value at line 1 column 1

I ran into a similar issue (see above), here's what I discovered:

When ETHERSCAN_API_KEY is set in the environment, forge will try resolving the etherscan API and fetch contracts info.
Even though the script being ran may not be broadcasting anything, is in offline mode and isn't being provided with the --verify flag, forge will still execute the previous step multiples times anyways.

TL;DR: unsetting ETHERSCAN_API_KEY when running local tests & scripts resolved my issue.

PS: the etherscan key must be commented out from the .env if using it, as unsetting the variable doesn't prevent forge from loading the environment file.

TL;DR: unsetting ETHERSCAN_API_KEY when running local tests & scripts resolved my issue.

This worked for me, though (probably because I was running from a script?) unset ETHERSCAN_API_KEY was insufficient, and I needed export ETHERSCAN_API_KEY="".

Correct, I edited my message to add this precision as it was indeed not specified.

Yes it's probably related to the same error. That's also what I had (i.e., Access denied).

Same issue with Holesky

Hey getting the same error what can i do

grandizzy · 2024-10-24T12:33:21Z

@slordua there were some changes for handling such, could you please let us now if you still facing the issue in latest version? thank you!

hernandp · 2024-10-31T01:58:23Z

Same problem here, running forge 0.2.0 (9501589 2024-10-30T00:22:24.244150356Z)

grandizzy · 2024-10-31T03:26:08Z

@hernandp can you share a way to reproduce the issue? Thank you

zerosnacks · 2024-10-31T09:18:42Z

I think this is all just related to receiving some kind of non-JSON formatted HTML error / gate page that Etherscan may throw. We could attempt to implement an error handler to give the user a more descriptive error but I don't see a practical way we can actually resolve this. It clearly happens sporadically and under certain conditions.

hernandp · 2024-10-31T15:19:05Z

@hernandp can you share a way to reproduce the issue? Thank you

It worked in Sepolia/Arbitrum Sepolia now, thanks.

In particular, Celo both Testnet/Mainnet does not support forge verify-contract and still displays this error.

grandizzy · 2024-10-31T15:39:30Z

thanks, is that celoscan to support this? @zerosnacks wdyt?

hernandp · 2024-10-31T16:06:43Z

@grandizzy @zerosnacks Sidenote, manual submission of data to Celoscan using generated JSON with --show-json-standard-input in forge command line works. So I guess is the RPC/HTTP interfacing which is failing.

slordua · 2024-10-31T16:15:37Z

@slordua there were some changes for handling such, could you please let us now if you still facing the issue in latest version? thank you!

sorry i'm not working in crypto anymore good luck guys

zerosnacks · 2024-10-31T17:02:51Z

Am able to reproduce it reliably on the Celoscan Alfajores testnet upon verification:

I'll reach out to Etherscan to see if we can get this fixed for Celo

Unfortunately it looks like there is no direct action Foundry can take here

@zerosnacks thank you.

0xV4L3NT1N3 · 2024-11-01T05:20:55Z

Looking into this from Etherscan's end!

zerosnacks · 2024-11-01T09:22:06Z

Thanks @0xV4L3NT1N3!

The HTML error that gets thrown originates from Blockscout due to a misclassification in the Alloy Chain's configuration, adding a fix here: alloy-rs/chains#109. Should land in Foundry soon.

In the meantime as a workaround @hernandp, please directly pass in the --verifier-url as follows: --verifier-url https://api-alfajores.celoscan.io/api with an accompanying --etherscan-api-key <API_KEY>.

zerosnacks · 2024-11-01T11:11:18Z

Fix has been merged into Foundry in: #9242

If you are running into a similar issue please leave a comment on this ticket, it is likely related to a misclassification of the explorer or an incorrect API URL
