When I try to init the app as given in docs, i see:

Do I need to run something special? I also tried to run this with the datastore emulator and even set DATASTORE_EMULATOR_HOST=localhost:8081

Hey, not sure what exactly is wrong here. Seems like a problem with Datastore. Can you check if you have everything installed properly: Cloud SDK, all the Cloud SDK extensions necessary, everything in requirements.txt etc.

Btw, I googled and found out that I had the same problem a year ago and opened this issue lol 😄 googleapis/python-ndb#220

Another one is here: googleapis/python-ndb#482

So the problem is very likely with the environment variables. Try setting all of the needed env vars, not just the DATASTORE_EMULATOR_HOST
