When I try running these example functions to connect to Cloud Datastore, I get a 401 Invalid Credentials error.
I'm running the go code from a VM within a Google Cloud Project. I have enabled the Datastore API and generated a JSON key which is loaded by the example code.
This question is very similar and even mentions the same repo, but does not use the same authentication shown in the examples, and was related to a 403 Unauthorized error.
For some reason the Datastore documentation does not mention go outside the context of App Engine.
