That is a bug... I've proposed a fix https://github.com/Shard-Labs/starknet-devnet/pull/283 even if I assume you did what you did for a good reason. I will argue that the `starknet_addInvokeTransaction` is not compliant with the v0,1 rpc spec the way it is coded right now. Also, sorry to not provide a set of tests but I do not write Python code at all!

Hello, I am facing an issue with `starknet-devnet (v0.3.1)` . I do not manage to run RPC `starknet_addInvokeTransaction` with positional parameters; yet it works with pathfinder and other vers like `starknet_estimateFee`. It returns `int() can't convert non-string with explicit base`. It is working fine on GOERLI. I have document the case on the repo https://github.com/Shard-Labs/starknet-devnet/issues/282. Does anyone have an example of a positional request to `starknet_addInvokeTransaction` on devnet that is working? The test inside the testsuite is also using named parameters. Thank you for your help

I used the Nethermind Warp Traspiler to translate the Solidity to Cairo successfully, but there was a problem with the test. I don't think there is this `warplib` package, `node_module` there is, but there is no python package. How do I generate python packages?


```python
from warplib.memory import wm_new
from warplib.maths.utils import felt_to_uint256
```

### How to represent / my environment
I used python virtual environment to develop cairo, and then I used this tool to convert solidity to cairo. After compiling, I reported an error and saw that `the warp-related package was not found`.
