thanks @imseananriley ! looks like there are some failing unit tests. please take a look at the contributing guide to see how to run local tests. You'll need to install mamba:

conda install -c conda-forge mamba

And do nox --list to see which test you want to run. For example:

nox -db mamba --envdir .nox-mamba -s "tests(extra='geopandas', pydantic='2.3.0', python='3.9', pandas='2.2.2')"
