UPDATE_COMPLETE_CLEANUP_IN_PROGRESS

From thease notes, I understand that your stack is stuck in “UPDATE_COMPLETE_CLEANUP_IN_PROGRESS” state and it is not changing the state. Hence you need guidance on how to move further. Please correct me if I misunderstood the case. m the case notes, I understand that your stack is stuck in “UPDATE_COMPLETE_CLEANUP_IN_PROGRESS” state and it is not changing the state.

I have investigated this, please allow me to share my findings.

To begin with, I have checked you stack “invokeA” status and found that at this moment it is in “UPDATE_COMPLETE” state. Hence, I believe that the issue is resolved. However, I have checked your stack events and found that the stack was trying to delete a resource “AWS::Lambda::Permission” with logical ID “HelloWorldFunctionHelloWorldPermissionProd”, but it was failing.

Also, I have checked that the time it took for your stack to transition between “UPDATE_COMPLETE_CLEANUP_IN_PROGRESS” to “UPDATE_COMPLETE” is around two hours.

Now, please allow me to explain why it took 2 hours to change the state of stack, whenever CloudFormation starts removing a resource, it will attempt to delete a resource three times before skipping the resource and continuing the cleanup process ie. when a resource fails to delete for the first time, then CloudFormation will again try to remove it 2 more times and if that also fails, it will skip that resource. Hence, it took almost 2 hours in this process. For more information regarding this issue, please check the document[1] and [2].

I hope above information have answered your query.

If you have any other queries, please write back to me, I will be more than happy to help.
