Debug Output
The debug output shows that the provider was able to create the SNS subscription successfully:
Immediately after creating the subscription, though, a call to
GetSubscriptionAttributesfor the subscription returns a 404 error, which leads to the Terraform apply failure:When I looked in AWS at the SNS topic after the failure, I saw that the subscription did actually exist, so this may just be an eventual consistency-related issue.
Panic Output
Expected Behavior
The apply should have succeeded.
Actual Behavior
Most of the time, the apply succeeds. In at least once instance, though, the
aws_sns_topic_subscriptionresource failed to apply, with this error:Note that if a second
terraform applyis attempted after the error occurs, theaws_sns_topic_subscriptionresource is created and the apply succeeds.Steps to Reproduce
