🤔 In thinking about this a lot more, I think this will actually be a breaking change for anyone who managed to import a listener default rule (then set priority = 99999 in their configuration to match). We would need to migrate their state and note the "breaking" change.

That said, I just verified its technically possible to have a default priority rule and a 50000 priority rule, so changing default rules to 50000 could also be confusing as its also "incorrect". 🤷‍♂️

Maybe the most correct answer here is changing the attribute to type string and accepting default priority, but only for import. Or having a separate, special aws_lb_listener_default_rule resource (the API does error if you try to delete default rules). This is all turning into a lot of work though 😓 .

I'm not sure how you'd want to proceed but the quick way to fix the actual validation except default rules is to leave default rules set to 99999 and go back to the custom validation function where it allows 99999 along with the correct priority range of 1 through 50000. 🤕

The following arguments are supported:

* `listener_arn` - (Required, Forces New Resource) The ARN of the listener to which to attach the rule.
* `priority` - (Required) The priority for the rule. A listener can't have multiple rules with the same priority.
* `priority` - (Required) The priority for the rule between `1` and `50000`. A listener can't have multiple rules with the same priority.
