multiple ec2s getting "var.subnet_ids is empty list of string"

[kataqatsi]

Describe the bug

Receiving this error on multiple ec2s before the build fails:

Error: Error in function call

  on main.tf line 12, in resource "aws_instance" "this":
  12:   subnet_id = length(var.network_interface) > 0 ? null : element(
  13:     distinct(compact(concat([var.subnet_id], var.subnet_ids))),
  14:     count.index,
  15:   )
    |----------------
    | count.index is 0
    | var.subnet_id is ""
    | var.subnet_ids is empty list of string

Call to function "element" failed: cannot use element function with an empty
list.

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

Expected behavior

After exporting my project to tf and installing dependencies, expected a successful build

Actual behavior

Build failure

[antonbabenko]

Thanks for opening this issue. Subnets are available in cloudcraft but not yet exported into terraform configurations by modules.tf, so you will have to specify subnet_id or subnet_ids arguments in ec2-instance layers.

I will keep this open as a reminder for myself when working on this project.
