multiple ec2s getting "var.subnet_ids is empty list of string" #53

Open kataqatsi opened 4 years ago

kataqatsi commented 4 years ago

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

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.
