evaluation_window_sec isn`t defined?

[aufkm]

Description
It appears that the evaluation_window_sec argument in the rate_based_statement block of the AWS WAFv2 module is not functioning as expected. Despite multiple attempts to set and update this argument, Terraform does not seem to recognize or apply the changes.

Steps to Reproduce
Initially set the evaluation_window_sec argument in the rate_based_statement block before deploying the infrastructure.
Deploy the infrastructure using Terraform.
Observe that the evaluation_window_sec argument does not take effect.
Attempt to update the evaluation_window_sec argument post-deployment.
Apply the changes using Terraform.
Notice that Terraform does not respond to the changes made to the evaluation_window_sec argument.

Expected Behavior
The evaluation_window_sec argument should be recognized and applied by Terraform both during the initial deployment and subsequent updates. The specified evaluation window should be set for the rate-based statements as intended.

Actual Behavior
Terraform does not recognize or apply the evaluation_window_sec argument. There is no change in the behavior of the rate-based statements when this argument is set or updated.

Additional Information
This issue is critical as it affects the rate-limiting behavior of our WAF rules, which is essential for our application's security and performance. Any assistance or insights into resolving this issue would be greatly appreciated.

Thank you.
