encodeParameters is broken on tuples

[cd1m0]

Expected behavior

Running this code should succeed:

const ethABI = require("web3-eth-abi");
ethABI.encodeParameters(["tuple(uint256,uint256)"], [[1,2]]);

Actual behavior

Running this code results in the below exception:

Uncaught AbiError: Parameter encoding error
    at Object.encodeParameters (/home/dimo/work/consensys/sol2maruir/node_modules/web3-eth-abi/lib/commonjs/api/parameters_api.js:67:15) {

Steps to reproduce the behavior

1. Install web3-eth-abi version 4.0.3
2. Run above code in node

Environment

Node 20

This is a bug and should be investigated and fixed. Thank you for helping to find it.

Additionally, for those who else would hit this issue: there is a workaround if you remove tuple and pass types in parens. An example:

const ethABI = require("web3-eth-abi");

console.log(ethABI.encodeParameters(["(uint256,uint256)"], [[1,2]]));
