System information

Previus Erigon version that we were using so far: 2.42.0 New Erigon version that we want to use: 2.48.1 (this is the version that does not work as expected, we do not know if the bug was present in previous ones between 2.42.0 and 2.48.1.

Chain/Network: mainnet

Expected behaviour

Execute trace_block to block 15630274 (mainnet) - It returns 503 elements

Actual behaviour

Execute trace_block to block 15630274 (mainnet) - It returns 502 elements

Steps to reproduce the behaviour

This is a duplicate of #7827, conclusion of which is: post-merge block rewards are no longer being returned as zero-value reward traces.

Starting from the merge (block number >= 15537394) value for these traces is 0x0:

{
  "action": {
    "author": "0xeee27662c2b8eba3cd936a23f039f3189633e4c8",
    "rewardType": "block",
    "value": "0x0"
  },
  "blockHash": "0x56a9bb0302da44b8c0b3df540781424684c3af04d0b7a38d72842b762076a664",
  "blockNumber": 15537394,
  "result": null,
  "subtraces": 0,
  "traceAddress": [],
  "type": "reward"
}

So the above is returned in trace_block results by v2.42.0, but not by v2.47.0+. Trace results for pre-Merge blocks should look the same, i.e block 15537393 has 4 total traces in both Erigon versions, and the trace reward has non-zero value:

{
  "action": {
    "author": "0x829bd824b016326a401d083b33d092293333a830",
    "rewardType": "block",
    "value": "0x1bc16d674ec80000"
  },
  "blockHash": "0x55b11b918355b1ef9c5db810302ebad0bf2544255b530cdce90674d5887bb286",
  "blockNumber": 15537393,
  "result": null,
  "subtraces": 0,
  "traceAddress": [],
  "type": "reward"
}
