Error invoking poseidon

[chancehudson]

Describe the bug Bug was originally reported in discord. Relevant text below

Hey folks, I'm playing with the LeanIMT. Having an issue with `InternalLeanIMT._insert()`.
It seems to work as expected on the first insertion, but fails with `Error: Transaction reverted without a reason string` on any subsequent insertions.
I'm sure there is something simple I've neglected, but whatever it is is not obvious to me.

Here's [the code I'm playing with](<https://github.com/gnosisguild/enclave/commit/456ff18fb1728bc4dbb33a05a3db6f759be95078>).
`yarn`
`yarn run`

Line `248` in `Enclave.sol` and line `988` in `Enclave.spec.ts`.

looks like it's failing here https://github.com/privacy-scaling-explorations/zk-kit.solidity/blob/main/packages/lean-imt/contracts/InternalLeanIMT.sol#L67 🤔

Additional context

Attempting to reproduce the issue here but have not been successful. I'd guess the bug is somewhere in the zk-kit stack. It may be related to the hardhat version, that's the only way i've seen the error.

Hardhat versions before 2.14.0 will error when building poseidon for solidity >= 0.8.20

Ran your repo in a codespace but pointed it at hardhat network rather than sepolia, got this error.

$ yarn test
yarn run v1.22.22
$ hardhat test ./test/a.test.js

So perhaps it's an issue with hardhat network?

[auryn-macmillan]

I was able to get my original code working with hardhat network by adding an override to the compiler settings and deploying the contract, rather than relying on the deterministically deployed contracts.

    overrides: {
      "node_modules/poseidon-solidity/PoseidonT3.sol": {
        settings: {
          optimizer: {
            enabled: true,
            runs: 2 ** 32 - 1,
          },
        },
      },
    },
