N/A
Description of changes:
There's an issue in cfn-guard where some nested maps can cause the loader to crash. This bug has been addressed in this PR and added a test case to verify this issue will not persist.
Currently when we
drainour stack for all the items, we assumed they'd all be string types (keys). This means we would only handle the case where the type was of string, and then we created an unreachable block. This is not true in the case of yaml that contains nested JSON/curly brace maps. To fix this we add a check to see if we have a map type, and if that is the case we just skip this iteration.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license
