AttributeError: module 'fiona' has no attribute 'path'

At friday I deployed a new staging version of the Earthquake Explorer - and there is currently an issue in starting shakyground.

Traceback (most recent call last):

For me it looks like a problem with the versions of geopandas and fiona - some kind of incompatibility.

The docker container don't start, so I need some more time to figure out the exact versions of the dependencies that are installed.

I guess with some version constraints we can get it back working.
