When I call for the Google Earth Engine (GEE) Python APIs through Google AppEngine, it throws out a HTTPException which says \"HTTPException: invalid and/or missing SSL cert
On the tracker for this GAE issue, the maintainers give a workaround:
As a temporary workaround, you can replace the expired urlfetch_cacerts.txt with https://curl.haxx.se/ca/cacert.pem
On linux you can use the following command: wget https://curl.haxx.se/ca/cacert.pem -O {Root of Python SDK}/lib/cacerts/urlfetch_cacerts.txt
