Terraform errors on aws_iam_server_certificate deletion

[bensojona]

When I try and delete an aws_iam_server_certificate resource that's being used by the aws_elb resource, I get the below error. This happens both when I do terraform destroy's and when I modify theaws_elb oraws_iam_server_certificate and it needs to replace the resource.

See .tf gist here.

Deleting the HTTPS listener that's using the SSL certificate seems to get be past the error, but obviously not a great solution.

I think this bug may be a duplicate of #3412, also worth a read is a similar issue but with apply #3275

Yep - dup of #3412, but these examples and descriptions are also helpful. 👍
