trace_ API disagrees with debug_ API

[s1na]

Expected behaviour

The call trace from debug_traceTransaction should agree with the call trace from trace_transaction. However we are seeing a difference. Please see also discussion: ethereum/go-ethereum#30593 for more context.

Actual behaviour

We can see the value of trace[1] in debug_ is reported as 0x2386f26fc10000 whereas in trace_ is reported as 0x16345785d8a0000.

Same with the state change tracer (using trace_replayTransaction). It is also reporting a higher state diff than it should. So when transaction is being replayed for some reason a higher value is being transferred than it should.

Hi, do you have any details on your setup? What version of Erigon are you running, are you running Erigon or rpcdaemon (if rpcdaemon, with or without datadir?), and your startup flags.

I'm guessing it is a similar issue to this: paradigmxyz/reth#11845. Basically in one of the endpoints the beacon root system call isn't applied prior to tracing.

Hey @shohamc1 👋

Details of that Erigon node:

• Version: thorax/erigon:2.60.8
• We are using rpcdaemon, with --datadir
• rpcdaemon args:
  • rpcdaemon --datadir=/data --private.api.addr=127.0.0.1:9090 --txpool.api.addr=127.0.0.1:9090 --http.addr=0.0.0.0 --http.port=8545 --http.vhosts=* --ws --metrics --metrics.addr=0.0.0.0 --metrics.port=6061 --http.api=eth,erigon,web3,net,debug,trace,txpool
• erigon args:
