Answer 1

You can give a try which below ..

I have encountered same issue before. There is catch in the template below where as per documentation it says clearly that it needs string thus you don't required !ImportValue here. just remove that, please look at the AWS DOC HERE

Secondly, there is also another problem in the below code as you defined the CoolingPeriod: 0 which is not correct as value can not be zero either it should be minimum 2 or greater.
