Google Apps Marketplace SDK : setup a contextual gadget

Ok, so without much notification given, adding market place listings to your vendor profile is no longer possible. The 'create new listing' button is greyed out.

I need to make changes to an existing marketplace listing but that gives errors. We are forced into the new SDK.

So I went ahead and enabled the apps market SDK, filled out all details including images of all sizes, add a COB extension for the contextual gadget and saved the whole thing.

A minute later I return to make a modification and dang... error: "We are looking into this.".

@Google: HELP !

UPDATE : I can reliably reproduce the error as explained here.

Enable Google Apps Marketplace SDK in your project
click on the gear icon, you will be directed to the old API Console
Fill out all details
Add a COB extension (Contextual gadget)
Save everything
Close the API console
Go back to your cloud console -> Google Apps Marketplace SDK
Click on the gear icon again
ERROR

Tested with several google accounts on different computeres and multiple projects on the cloud console.

Solution

You must fill out parameter name and a paramter value or your cloud console will return errors and you will not be able to recover from this.

Ouch, that were 3 useless weeks....
