I used to be able to deploy cloud functions, but not anymore it seems.
Steps:

1. Click “Create function” in https://console.cloud.google.com
2. Leave everything default -> next -> deploy

Deployment starts and finishes with errors:

This function has failed to deploy and will not work correctly. Please edit and redeploy. 

Cloud Run service projects/random-360814/locations/us-central1/services/function-1 for the function was not found. The function will not work correctly. Please redeploy.

Build failed with status: FAILURE and message: An unexpected error occurred.
