method handler crashed when calling `trace_block` on ETH Goerli

[johnhckuo]

System information

Erigon version: v2.52.5

OS & Version: Linux

Erigon Command (with flags/config): ./build/bin/erigon --http.api=eth,engine,erigon,web3,net,debug,trace,txpool,parity

Consensus Layer: none

Chain/Network: ETH Goerli

Expected behaviour

trace_block should return successfully with correct block number

Actual behaviour

rpc error:

{"level":"ERROR","timestamp":"2023-10-20T04:03:16.853Z","file":"ledger/transaction.go:1135","message":"getBlockTraceTxs with block 9897666, error &rpc.jsonError{Code:-32000, Message:\"method handler crashed\", Data:interface {}(nil)}","tag":"ledger","coin":"goerli"}

Erigon node error log:

[EROR] [10-20|08:32:06.195] RPC method trace_block crashed: interface conversion: *cli.remoteConsensusEngine is not consensus.Engine: missing method APIs

Steps to reproduce the behaviour

Starts up Erigon v2.52.5, and curl trace_block endpoint on Goerli with correct block number, then node will panic.

Are you running rpcdaemon separately? Are you giving it --datadir flag?

Faced the same issue. I was running rpcdaemon as a separate container, and the fix was to add --datadir and use tini to run rpcdaemon. Need to have a different pid than erigon process - otherwise you'll get the below error:
