Expected behaviour

debug_traceCall should succeed (no error).
This same call worked on Erigon v3.0.17.

Actual behaviour

debug_traceCall method returns:
{"jsonrpc":"2.0","id":1,"result":null,"error":{"code":-32000,"message":"incorrect number of top-level calls"}}

Steps to reproduce the behaviour

Run the following request against Erigon v3.1.0 on Gnosis:

curl --request POST \
  --url http://127.0.0.1:8545 \
  --header 'Content-Type: application/json' \
  --data '{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "debug_traceCall",
  "params": [
    {
      "from": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
      "to": "0x0000000000a39bb272e79075ade125fd351887ac",
      "data": "0xd0e30db0"
    },
    "latest",
    {

    }
  ]
}'
