Tried using the CDBlueGreen.yaml from this repo in CloudFormation but it won't work.

Have you solved this error??
I also got this error.

There is a workaround to overcome this issue.

1. Get the userdata which is been passed to the EC2 instance, copy the last command related to CFN signal
2. SSH to instance
3. Execute the command which is copied as part of step 1. ( cfn-signal -e 0 -r 'BlueGreen configuration' --stack xxxxxxxx)

• Similarly follow above steps for second instance as well.
• later you need to follow these steps for the third instance (bluegreen-workstation) which would be launched as part of a different ASG.
