[Bug]: Creating resource aws_wafv2_web_acl_association in same config as aws_wafv2_web_acl often raises WAFUnavailableEntityException

[bunmikAgency]

Terraform Core Version

1.3.7

AWS Provider Version

4.49.0

Affected Resource(s)

• aws_wafv2_web_acl_association

Expected Behavior

Deploy a Load Balancer with a WAF ACL in front of it.

Actual Behavior

Almost half of the time (I tried around 10 times) Terraform errors with WAFUnavailableEntityException. This is already a RetryError in the TF AWS provider code, but presumably the time between ACL creation and load balancer association is still not long enough to get this reproducibly correct.

Relevant Error/Panic Output Snippet

module.waf.aws_wafv2_web_acl_association.load_balancer: Still creating... [5m1s elapsed]

│ Error: creating WAFv2 WebACL Association (arn:aws:wafv2:xx-xxx-x:xxxxxx:xxxxxxx,arn:aws:elasticloadbalancing:xx-xxx-xx:xxxxxxxxx): WAFUnavailableEntityException: AWS WAF couldn’t retrieve the resource that you requested. Retry your request.

Terraform Configuration Files

resource "aws_wafv2_web_acl_association" "example" {
  resource_arn = aws_lb.example.arn
  web_acl_arn  = aws_wafv2_web_acl.example.arn
}

resource "aws_wafv2_web_acl" "example" {
  name  = "alb-example"
  scope = "REGIONAL"

  # some more irrelevant config goes here
}

resource "aws_lb" "example" {
  name = "example"

  # some more irrelevant config goes here
}

Steps to Reproduce

This issue was raised about 1 year ago where timeout is increased from 2 minutes to 5 minutes and looks like it is still not enough to perform this action.

The same happened to me. I have added a depends_on section on the aws_wafv2_web_acl_association.

Since often is a keyword here, not sure if that solved the issue 🤔

💥 I'd suggest giving more attention to this item since it's a pretty basic thing to do...

I've just looked at the implementation code for this and the timeout is hardcoded at 5 minutes. I think the solution is to add configurable timeouts on the resource in the same way as for things like RDS instances.

depends_on wouldn't help here, since depends on resources are implicitly defined.
