Unknown Exception with Code: 13

问题:

I have created a new project, then went to VM Instances. It says "enabling compute engine". After some time, it throws the following error:

Unknown Exception with Code: 13. 

Why am I receiving this error? Do I have to set up permissions or anything else?

In some cases that error occurs because your project doesn't have a billing account assigned. You can check if this is your problem in the left menu Billing -> Manage Billing Accounts from drop down box.
