Engine RPC API not available

[yakimant]

Hi guys,

I'm new to Erigon. Here is an example for engine_newPayloadV2 RPC method:

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32601,
    "message": "the method engine_newPayloadV2 does not exist/is not available"
  }
}

Although I can see it should be available:
https://github.com/ledgerwatch/erigon/tree/devel/cmd/rpcdaemon

I run with --http.api=eth,net,erigon,admin,engine

Thanks!

1. maybe you mess up with * - it's special character in shell and can destroy flags parsing.
2. maybe you didn't configure --authrpc

Just checked the full command - doesn't contain any * char.

• --http.addr=0.0.0.0 --http.port=8545
• --http.api=eth,net,erigon,admin,engine
• --authrpc.addr=0.0.0.0 --authrpc.port=8551 --authrpc.jwtsecret=/keys/jwtsecret

This is how I test RPC method:

curl -X POST --silent --max-time 5 --show-error --fail-with-body -H Content-type:application/json --data '{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "engine_newPayloadV2",
  "params": []
}' http://0.0.0.0:8545/

Do I understand correctly, that I should use auth.rpc port for all engine methods?
