Hi, same issue here, the variables self.pypi_lookup and self.conda_lookup seems to be deleted before assignment. A temporary workaround is editing the lookup.py file to remove :

        del self.pypi_lookup
        del self.conda_lookup

A way to reproduce the problem is to create a pyproject.toml from https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#a-full-example then calling : conda-lock lock --file pyproject.toml --pypi_to_conda_lookup_file https://raw.githubusercontent.com/regro/cf-graph-countyfair/master/mappings/pypi/grayskull_pypi_mapping.yaml --platform win-64 --lockfile conda-lock.yml

Thanks !
