I also got an error message that an additional agent property was not serializable.
A possible workaround might be to implement a custom geo_interface method:

    def __geo_interface__(self):
        """
        Override the default __geo_interface__ method of GeoAgent to resolve some serialization issues.

        Return a GeoJSON Feature.

        Removes shape from attributes.
        """
        properties = dict(vars(self))
        properties["model"] = str(self.model)
        shape = properties.pop("shape")

        properties.pop("site")  # <= removes site because it is not serializable 

        shape = transform(self.model.grid.Transformer.transform, shape)

        return {"type": "Feature", "geometry": mapping(shape), "properties": properties}

In your custom __geo_interface__ method, what if properties is changed into an empty dictionary? That is, to get rid of all attributes:

return {"type": "Feature", "geometry": mapping(shape), "properties": properties}

into

return {"type": "Feature", "geometry": mapping(shape), "properties": {}}

Subsequently the useful properties will be set in the render() function of MapModule. In this way hopefully only the necessary fields are sent to frontend for visualization.
