Thanks for reporting this!
Can you let us know the endpoint for the Cloud backend created, while trying out the quick-start guide and sample apps? We’re actively investigating reports of issues with backend creation in specific AWS regions, which we suspect, could lead up to the silent errors seen. With your backend info, we’d be able to quickly help get you get back on track with the tutorials. You can open a support ticket through the Cloud dashboard > ‘Support’ option in the left nav-bar if you’d like to keep the backend details private.
As @amaster507 pointed out, the public examples from the DQL docs fail to run as well, but we are working on restoring this functionality on a priority.
If you prefer, we’re happy to have a conversation to get introduced, learn about your use-case(s) and address any roadblocks with your evaluation of Dgraph. Feel free to write to us at contact@dgraph.io.
