HTTPException: invalid and/or missing SSL certificate for url: https://accounts.google.com/o/oauth2/token

Question

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

Answer 1

For Windows, because the SDK is stored in an Admin Read-only area, I used Windows File Explorer in two steps instead of a script.

First download https://curl.haxx.se/ca/cacert.pem to a folder, e.g. Downloads.

curl https://curl.haxx.se/ca/cacert.pem > urlfetch_cacerts.txt

You can also use a browser to download the file and rename it.

Check where your cacerts are stored. I found them in

C:\Program Files (x86)\Google\google_appengine\lib\cacerts

Others report it in:

C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\lib\cacerts\urlfetch_cacerts.txt 

With Admin credentials, rename the file urlfetch_cacerts.txt to something else.

Then copy the downloaded file cacerts.pem to

C:\Program Files (x86)\Google\google_appengine\lib\cacerts

And rename it to urlfetch_cacerts.txt

Voila!
