Expected behaviour

Return trace of the block hash for following API:

curl localhost:8545   -X POST   -H "Content-Type: application/json"   --data '{"method":"debug_traceBlockByHash","params":["0x36e62d559fc61c55bc5bef9ee619db1d65fb946c6e7c100fa74164a4701e0e04", {"tracer": "callTracer", "tracerConfig": {"onlyTopCall":false,"withLog":true}}],"id":1,"jsonrpc":"2.0"}'

Actual behaviour

Handler crashes and response ends with

,{"result":{"from":"0x4714f276709b44c7b3174cee99ed95610f3be3fd","gas":"0x0","gasUsed":"0x5208","to":"0x4432704147b8ec64ea23f6202e1dfd036167f0f6","input":"0x","value":"0x2c68af0bb140000","type":"CALL"}},{"result":null,"error":{"code":-32000,"message":"method handler crashed"}}

Steps to reproduce the behaviour

make the call to bsc erigon node:

curl localhost:8545   -X POST   -H "Content-Type: application/json"   --data '{"method":"debug_traceBlockByHash","params":["0x36e62d559fc61c55bc5bef9ee619db1d65fb946c6e7c100fa74164a4701e0e04", {"tracer": "callTracer", "tracerConfig": {"onlyTopCall":false,"withLog":true}}],"id":1,"jsonrpc":"2.0"}'

add this flag in your start command: --http.api=web3,net,eth,debug,trace,txpool

[mateipopp]

Hey @blxdyx , the flags mentioned are present and the error still persist

[blxdyx]

It's test fine in my case.
curl --location --request POST 'localhost:8545' --header 'content-type: application/json' --data-raw '{"method":"debug_traceBlockByHash","params":["0x36e62d559fc61c55bc5bef9ee619db1d65fb946c6e7c100fa74164a4701e0e04", {"tracer": "callTracer", "tracerConfig": {"onlyTopCall":false,"withLog":true}}],"id":1,"jsonrpc":"2.0"}'

Maybe could be related to my node data? Would be possible to have a BSC snapshot for testnet?

[blxdyx]

We will upload it soon.
