How to activate Multi-AZ option.

[zhixiangjoy]

Describe the Bug

By default, I create a redis cluster, but I can't find how to active the Multi-Az option.

Expected Behavior

How can I do it , Thanks a lot !

it looks like the option was not added in the code. Basically the resource aws_elasticache_replication_group.default is missing the option multi_az_enabled. There is an open PR about it pending approval...
#109

Pr #109 got merged but not working locally:

Acquiring state lock. This may take a few moments...

Error: Unsupported argument

  on .terraform/modules/redis/main.tf line 91, in resource "aws_elasticache_replication_group" "default":
  91:   multi_az_enabled              = var.multi_az_enabled

An argument named "multi_az_enabled" is not expected here.

Releasing state lock. This may take a few moments...

@gregory not sure what's going on here, maybe a Terraform version issue? Here's their own doc with that arg for reference:

I just ran into this as well. Here's the PR where it was added, you need the AWS provider 3.26.0 or later.
