I had the same issue/error with cloudformation. For me it was because I was creating an Aurora(MySql) cluster with two instances in the cluster and I was passing the wrong parameters to the Instances. Because I had the wrong properties, AWS was viewing the Instances as stand alone and was giving me this error. Check each property on which you need for clusters or instances:

You need to add this configuration under your cloudformation template, Even if you specify DBcluster you need to add username and password in you individual DBInstance as well.

MasterUsername="Username",
MasterUserPass="Password",

In my case the problem was because of the characters in username and password. AWS doesn't allow you to use - in database username and also it doesn't allow you to use @/ etc in the password.
