Error: Invalid count argument

[ProxiBlue]

Hello,

Any idea what is wrong? Worked once, destroyed once, then on any further retries:

11:55 $ terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

data.template_file.installation_template: Refreshing state...
data.aws_availability_zones.all: Refreshing state...

Error: Invalid count argument

  on .terraform/modules/es/main.tf line 30, in resource "aws_elasticsearch_domain" "es":
  30:   count = false == local.inside_vpc ? 1 : 0

The "count" value depends on resource attributes that cannot be determined
until apply, so Terraform cannot predict how many instances will be created.
To work around this, use the -target argument to first apply only the
resources that the count depends on.
