I am reopening this issue.
Today morning I got it. I am not sure the reason why it is happening, but here the code that I am using.

module "waf" {
  source = "github.com/trussworks/terraform-aws-waf"

  alb_arn                             = module.alb.this_lb_arn
  associate_alb                       = true
  blocked_path_prefixes               = ["/admin", "/password"]
  allowed_hosts                       = ["apples", "oranges"]
  wafregional_rule_f5_id              = ""
  web_acl_metric_name                 = "prod_alb_acl_metric_name"
  web_acl_name                        = "prod_alb_acl"
}

Here is the error message received:

This is likely due to the character requirements in the web_acl_name. They don't allow _
