Important Factoids

After a bit of digging, it seems the rule TYPE argument is not supported in wafregional_web_acl (although it IS supported is waf_web_acl). Without this argument, it is not possible to reference a RATE_BASED rule.

References

See https://docs.aws.amazon.com/waf/latest/APIReference/API_regional_ActivatedRule.html:

TYPE: Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

The aws_wafregional_web_acl resource support for rule type has been merged into master via #4978 and will release with version 1.25.0 of the AWS provider, likely middle of this week. Please note you must configure this new attribute for RATE_BASED rules.
