Cannot read property 'aclState' of undefined

What version of Dgraph are you using?

master branch

Have you tried reproducing the issue with the latest release?

Yes; i'm on master.

What is the hardware spec (RAM, OS)?

24GB, Windows 10

Steps to reproduce the issue (command/config used to run Dgraph).

Go to https://play.dgraph.io/?dev or https://play.dgraph.io/?latest and type anything into the "Dgraph server URL" input box, on the Dgraph Server Connection modal. The screen will go white and I receive the following error in the console.

TypeError: Cannot read property 'aclState' of undefined

Expected behaviour and actual result.

Should be able to type in the input box without the screen going blank.
