availability_zone_count when we set to 3 getting an error

[lakshmiramaswamy]

Describe the Bug

availability_zone_count we are not able to set to 3.. Its just taking value as 2 ..

Error:
ValidationException: You must choose an even number of data nodes for a two Availability Zone deployment

Even in document, I see it's specified either 1 or 2.. but in AWS Console we have an option of choosing 3 AZ...

Expected Behavior

It should accept 3 az for availability_zone_count..

Steps to Reproduce

zone_awareness_enabled = true
availability_zone_count = 3
subnet_count = 3
dedicated_master_enabled = true
dedicated_master_count = 3

Environment

No response

Additional Context

In AWS CONSOLE we do have option choose as 3 AZ and instance count as 3. But this module is not letting us to do with it
