Seeing "Unknown error when simulating validation on entry point" during eth_estimateUserOperationGas

[ska1296]

I am trying to estimate gas on entry point address '0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789". It is returning:

"Unknown error when simulating validation on entry point. Error message: UnknownErr(\"Unknown middleware error: JsonRpcClientError(SerdeJson { err: Error(\\\"response must be either a success/error or notification object\\\", line: 1, column: 206), text: \\\"{\\\\\\\"jsonrpc\\\\\\\":\\\\\\\"2.0\\\\\\\",\\\\\\\"id\\\\\\\":319866,\\\\\\\"result\\\\\\\":null,\\\\\\\"error\\\\\\\":{\\\\\\\"code\\\\\\\":-32000,\\\\\\\"message\\\\\\\":\\\\\\\"tracing failed: fee cap less than block base fee: address 0x0000000000000000000000000000000000000000, gasFeeCap: 0 baseFee: 11\\\\\\\"}}\\\\n\\\" })\")"

I am using a paid plan of quicknode provider and it supports debug_traceCall.

I am starting the bundler using:

cargo run --release -- bundler --eth-client-address <mu_quicknode_url> --mnemonic-file ${HOME}/.silius/<file_name> --beneficiary 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 --entry-points 0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789 --http --ws --http.port 4000 --chain goerli

I have an erigon node running on the same machine (OS: Ubuntu 23.04) with the following config in config.toml file:

datadir = "/home/otter/erigon/data" 
port = 1111
chain = "goerli"
http = true
"private.api.addr"="0.0.0.0:9090"
"http.api" = ["eth","debug","net","web3","erigon","trace"]

When I turn of erigon sync, I see a different error:

{"jsonrpc":"2.0","error":{"code":-32603,"message":"Unknown error when simulating validation on entry point.

Hmm, seems there can be some problems with using erigon client. Stackup bundler had to add something to support it: stackup-wallet/stackup-bundler#299

The error:

Great. Then we can close this issue since we tracking the client compatibility problem in #227
