ValueError: Expected exactly one contract key, found /path/mox-cu/mox-favorites-cu/src/favorites.vy, extra_data

I'm getting this error:

  File "/path/.local/share/uv/tools/moccasin/lib/python3.13/site-packages/boa/interpret.py", line 87, in create_module
    ret = load_partial(self.path)

ValueError: Expected exactly one contract key, found /path/mox-cu/mox-favorites-cu/src/favorites.vy, extra_data

Here is how you can reproduce it:

python -m venv ./.venv
source .venv/bin/activate
pip install titanoboa-zksync # or `uv add titanoboa-zksync`
pip install "vyper==0.4.0" # or `uv add "vyper==0.4.0"`
echo "# pragma version 0.4.0/nhi: uint256" > my_contract.vy
python

Then, in your python shell:

>>> import boa_zksync
>>> import boa
>>> boa_zksync.set_zksync_test_env()
>>> boa.load("my_contract.vy")

You'll get the error.

Oh. It looks like it's fixed here:

we just need to cut a release.
