RPC Methods Are Broken, Slow, or Crash the RPC Nodes - BlockPi Report

[CharlieMc0]

These RPC methods either don't work or can cause the node to lock up and/or crash when used.

Reported by BlockPi

method	problem	suggestion
/cosmos/params/v1beta1/params	invalid request, seems to be an old method already abandoned	delete this method
/ethermint/evm/v1/trace_tx	error "runtime error: invalid memory address or nil pointer dereference: panic",	not open to users, or fix
/zeta-chain/crosschain/cctx	response data too large, has parameter choice	not open to users, or only available with parameters
/zeta-chain/crosschain/cctxPending	response data too large, and has no parameter choice	not open to users, or add parameter choice
/zeta-chain/crosschain/keygen	not working, and description says there is an index parameter	to be fixed
/zeta-chain/crosschain/gasBalance/{index}	gasBalance has no content	will re-test when athena-3

thanks @CharlieMc0

5th/6th will be fixed in athens3

3rd/4th not sure; they are needed by zetaclients but perhaps not by third party apps or services. Maybe blockpi can disable them.

2nd: @aldapp7 any comment?

1st: @fadeev @kingpinXD may be able to comment.

2nd, not sure, never tested that and it wasn't in the scope on updating Ethermint rpcs, I will take a look.

1st: I believe the params module has been deprecated.

Sounds good. I imagine that your PR on OpenAPI generation remove this endpoint?

[fadeev]

That PR was focused on serving existing OpenAPI spec. If we merge the buf PR, I can add buf-based OpenAPI spec generation that will remove this endpoint (and just provide more reliable spec generation process).

@brewmaster012 @CharlieMc0 2nd unlikely be able to fix, issue goes deep into ethermint x/types, which we obviously don't want to fork and tweak to our own (too large to support it just for this rpc), fails here https://github.com/zeta-chain/zeta-node/blob/develop/rpc/backend/tracing.go#L115 -> uses evmtypes.QueryClient https://github.com/zeta-chain/zeta-node/blob/develop/rpc/types/query_client.go#L38 which is imported from https://github.com/zeta-chain/zeta-node/blob/develop/rpc/types/query_client.go#L28

Closing as it seems no longer relevant with the current state of the project. Feel free to reopen it.
