Versions

Steps to reproduce

1. Send JSON-RPC call to the archival node - totalSupply() method via eth_call and debug_traceCall
   eth_call

curl  http://10.3.155.147:10131  -X POST  -H "Content-Type: application/json"  --data '{"id":1,"jsonrpc":"2.0","method":"eth_call","params":[{"from":"0xb04a7f2Cd74Eb624Df4BD8bed8f7034B5Aed89C0","to":"0x3bcDb2642cBC0d351F6Bc7fDFEA50120cE9146AC","data":"0x18160ddd0000000000000000000000000000000000000000000000000000000000000000"},"latest"]}'

debug_traceCall

curl  http://10.3.155.147:10131   -X POST  -H "Content-Type: application/json" --data '{"id":1,"jsonrpc":"2.0","method":"debug_traceCall","params":[{"from":"0xb04a7f2Cd74Eb624Df4BD8bed8f7034B5Aed89C0","to":"0x3bcDb2642cBC0d351F6Bc7fDFEA50120cE9146AC","data":"0x18160ddd0000000000000000000000000000000000000000000000000000000000000000"},"latest"]}'

2. check the result

Actual state:
Eth-call returns the total supply value 0x000000000000000000000000000000000000000000000000000000003b9aca00
debug_traceBlock returns: INVALID_PARAMS: Invalid method parameters (invalid name and/or type) recognised error

Expected behavior
Skaled should return the number of possible tracing result by executing an eth call within the context of the given block execution.

request regular eth_call

curl  http://1.1.1.1:10131  -X POST  -H "Content-Type: application/json"  --data '{"id":1,"jsonrpc":"2.0","method":"eth_call","params":[{"from":"0xb04a7f2Cd74Eb624Df4BD8bed8f7034B5Aed89C0","to":"0xE6A2c576a7759300207D7F5Bf607336635737176","data":"0x18160ddd0000000000000000000000000000000000000000000000000000000000000000"},"latest"]}'

UPD
Partially fixed on 3.17.2-develop.3-historic

need to add a handler for the absence of an empty object in the params field.

But, according to the documentation https://geth.ethereum.org/docs/interacting-with-geth/rpc/ns-debug, JSON RPC call should be valid without the empty object

But, according to the documentation https://geth.ethereum.org/docs/interacting-with-geth/rpc/ns-debug, JSON RPC call should be valid without the empty object

> curl -H "Content-Type: application/json" -X POST  localhost:8545 --data '{"jsonrpc":"2.0","method":"debug_traceCall","params":[null, "pending"],"id":1}'

will be fixed in a separate issue #1780
