I want to create a

waf

with rate limit rule, I try to create a

RuleGroup

but I got error for this line of code:

action=pulumi_aws.wafv2.RuleGroupRuleActionArgs(
                    allow=pulumi_aws.wafv2.RuleGroupRuleActionAllowArgs(),
                ),

Here is the code:

import pulumi
import pulumi_aws


def create_rate_limit_rule(
        deploy_name_prefix,
):
    """
    :param deploy_name_prefix:
    :return:
    """
    rate_based_rule = pulumi_aws.wafv2.RuleGroup(
        f'waf-rule-group{deploy_name_prefix}',

        scope="REGIONAL",
        rules=[
            pulumi_aws.wafv2.RuleGroupRuleArgs(
