rootchain and supernet commands are not working on anvil becuases of of " failed to get fee history"

[RonTuretzky]

[ Binary command such as rootchain deploy, polybft supert not working on Anvil Goerli fork ]

Description

I am running an anvil goerli fork like so

anvil --fork-url https://goerli.infura.io/v3/9aa3d95b3bc440fa88ea12eaa4456161 --host 0.0.0.0	> /dev/null 2>&1 &

and the following command

./polygon-edge rootchain deploy \ 
  --stake-manager ${stakeManagerAddr} \
  --stake-token ${stakeToken} \
  --proxy-contracts-admin ${proxyContractsAdmin} \
  --json-rpc $ROOTCHAIN_RPC_URL \
  --deployer-key $PRIVATE_KEY 

fails with

failed to deploy rootchain contracts: failed sending CustomSupernetManager contract deploy transaction: failed to get fee history: {"code":-32602,"message":"invalid type: null, expected a sequence"}

similarly

finalizing genesis validator set failed. Error: failed to get fee history: {"code":-32602,"message":"invalid type: null, expected a sequence"}

Environment

• MacOS 14.1.1 (23B81)
• Polygon Edge 1.3.1
• Branch : Official Release 1.3.1
• Ran Locally

Steps to reproduce

Run the anvil command
Attempt to follow the rest of the polygon edge deploy steps

Expected behavior

Deployment should proceed as expected

@Stefan-Ethernal any insight would be appreciated 🙏🏻

[RonTuretzky]

ran this

cast rpc eth_feeHistory '[3, "latest", []]' --raw 

with the following result

{"baseFeePerGas":["0x8","0x8","0x8","0x7"],"gasUsedRatio":[0.056730833333333335,0.0219493,0.12383936666666667],"oldestBlock":"0x9cab53"}
so it seems like the rpc endpoint is working, what is the binary expecting?

[RonTuretzky]

seems like in txrelayer/txrelayer.go line 158

if txn.MaxFeePerGas == nil {
	// retrieve the latest base fee
	feeHist, err := t.Client().Eth().FeeHistory(1, ethgo.Latest, nil)
	if err != nil {
		return ethgo.ZeroHash, fmt.Errorf("failed to get fee history: %w", err)
	}

is what's causing the error, with the "invalid type: null, expected a sequence" , perhaps addresed to the "nil" value in line 160

although this test

https://github.com/umbracle/ethgo/blob/6b068360fc975016cdace38cda309e93f3329181/jsonrpc/eth_test.go#L424

seems to suggest that's not the problem

Maybe Anvil Goerli client, to which you are sending the given JSON RPC request is not handling nil values for reward percentiles properly.
Since Edge is not actively maintained anymore, can you try with forking the repository and changing the following line this way (providing an empty array instead of nil?

feeHist, err := t.Client().Eth().FeeHistory(1, ethgo.Latest, []float64{})

Also, it probably makes sense to report the issue to the Anvil Goerli client as well, so they can take a look on their side as well, how they are handling nil reward percentiles parameter.

I did end up doing that and it worked! Thank you. Will submit an issue to foundry as well.

Will there be future releases to polygon edge or is this end of the line for the product?

Unfortunately, this is the end for the Edge. Officially it is now treated as the community project and seems like Polygon does not have interest in maintaining it anymore. This is the blog post that elaborates it (https://polygon.technology/blog/polygon-labs-to-focus-contributions-on-polygon-cdk-discontinues-contributions-for-edge).

Thank you for all your hard work!
