WAF Error: WAFUnavailableEntityException

Question

When trying to create a WAF web ACL, I get the following error: "WAFUnavailableEntityException: AWS WAF couldn't retrieve the resource that you requested. Retry your request."

[This page in the AWS Documentation](https://docs.aws.amazon.com/waf/latest/APIReference/API_CreateWebACL.html) gives the following explanation:

"WAFUnavailableEntityException
AWS WAF couldn’t retrieve a resource that you specified for this operation. If you've just created a resource that you're using in this operation, you might just need to wait a few minutes. It can take from a few seconds to a number of minutes for changes to propagate. Verify the resources that you are specifying in your request parameters and then retry the operation. HTTP Status Code: 400"

However, I waited for over an hour after creating my resources (first, an API, then an ALB), and I am still getting the same error when I try to create a web ACL for those resources.

Not sure what the issue is.

Accepted Answer

I'm glad to hear that the issue has been resolved.
This error message appears when the WAF service is unable to find or access the specified resource. This might happen because the resource was deleted or is not in the same region as the WAF service, or because the resource is not properly configured.

Answer

Wow. It really was a timing issue. I had to wait over two hours, but was finally able to add my resources to my web ACL.
