Missing project documentation on PyPI

I am planning on submitting cellphonedb to the bioconda-recipes repository. I am using conda's skeleton command to pull information from the PyPI repository and automatically build the recipe. However, I am encountering this error:
$ conda skeleton pypi --version 2.1.5 --python-version 3.7 cellphonedb

AttributeError: 'NoneType' object has no attribute 'replace'
From what I can see, the error is caused by the empty summary section of the PyPI repository. Would it possible for someone on the team to flesh out the PyPI repository?
