Set/change your product name, I had this issue until I created a product name as same as project name.

The product name can be set in the Consent screen section of the Google Developers Console for your project. Look under APIs &amp; auth in the left navigation and select Consent screen.
You need also to set your email address in the box above the product name.

Another thing to check:

Check that any original values are still in place, and remove dummy entries.
