debug_traceTransaction breaking the node

[tclemos]

const txHash = "0xb6a8741e3dd6da5f49b15a3dfdab08e71c1fc3d2f49feef11e5ae1c4d0a4f603";
const res = await provider.send("debug_traceTransaction", [txHash]);
console.log(res);

The RPC seems to crashes with the next error:

Error: processing response error (body="{\"jsonrpc\":\"2.0\",\"id\":42,\"error\":{\"code\":-32000,\"message\":\"failed to get trace\"}}", error={"code":-32000}, requestBody="{\"method\":\"debug_traceTransaction\",\"params\":[\"0xb6a8741e3dd6da5f49b15a3dfdab08e71c1fc3d2f49feef11e5ae1c4d0a4f603\"],\"id\":42,\"jsonrpc\":\"2.0\"}", requestMethod="POST", url="https://rpc.internal.zkevm-test.net/", code=SERVER_ERROR, version=web/5.7.1)

Hi, how do you enable the debug_* api on a zkEVM node? I couldn't find those settings in the doc, and seems it's disabled by default (at least for me).

hi @ymonye, you need to set the --http.api flag with all the API groups you want exposed by the jRPC Server, here is an example:
https://github.com/0xPolygonHermez/zkevm-node/blob/a2e3c524671fc64a6054a116fa53886ad50071ba/test/docker-compose.yml#L298

--http.api eth,net,debug,zkevm,txpool,web3

Thank you so much! That worked. I really appreciate you getting back to me as well
