[Bug] ordered_cache_behavior not present throwing an error #178
Description
Description
Error: Invalid function argument
│
│ on ..\main.tf line 538, in locals:
│ 538: cache_behaviors = concat([var.default_cache_behavior], var.ordered_cache_behavior)
│ ├────────────────
│ │ while calling concat(seqs...)
│ │ var.ordered_cache_behavior is null
│
│ Invalid value for "seqs" parameter: argument must not be null.
This error only happens in version 6.0.0; in version 5.2.0, everything works.
I think this is because the "ordered_cache_behavior" is defaulted to "null" and concat expects only lists.
Version 5.2.0 item in wrapper:
ordered_cache_behavior = try(each.value.ordered_cache_behavior, var.defaults.ordered_cache_behavior, [])
Version 6.0.0 item in wrapper:
ordered_cache_behavior = try(each.value.ordered_cache_behavior, var.defaults.ordered_cache_behavior, null)
So the solution is either to return an empty list as before or to use a different Terraform function.
