You are seeing this error because Fn:Select is trying to reference an index in an array/list that does not exist.
Now WHY you are getting this error is a larger issue that requires a bit of digging around. We need to figure out why a result from Fn:GetAZs is returning a result without a value at index position 1.
Can you please get back to us on the following:
- What region are you running this in where you see the error?
- Can you please run "aws ec2 describe-availability-zones" in the same region you are launching the stack and give us the output?
- Try changing the index in the Fn:Select from 1 to 0 and update/re-launch the stack. Do you get the same error or a different error (i.e. do you now get "Availability Zone cannot be null")? Please make sure that you change all of the occurrences in the template.
