Answer 1

There is no such constraint!

The first error clearly says that it could NOT create that constraint since the datatypes of those two columns involved (Game.Id and Tester.Game) do not match.

What you should do is check how you're creating your FK constraint that leads to that first error - and explicitly give that FK constraint a meaningful name!
