Terraform Version

Terraform v0.11.13

  • provider.aws v2.6.0
  • provider.kong v1.9.2

Not on 4.5.0 due to older version of Kong (0.10.2)

Affected Resource(s)

API Resource.

Terraform Configuration Files

resource "kong_api" "terraform-test-api" {
    name                     = "terraform-test-api"
    hosts                    =  []
    uris                     = [ "/v3/terraform-test-api" ]
    methods                  = [ "GET", "POST" ]
    upstream_url             = "http://UPSTREAM-URL"
    strip_uri                = true
    preserve_host            = false
    retries                  = 3
    upstream_connect_timeout = 60000
    upstream_send_timeout    = 60000
    upstream_read_timeout    = 60000
    https_only               = false
    http_if_terminated       = true
}

Debug Output

* kong_api.terraform-test-api: failed to create kong api: &{0xc420394da0 [] [0xc420394eb0] [0xc4203a6520 0xc4203a6530] 0xc420394ff0 0xc42009dc28 0xc42009dc29 0xc42009dcb0 0xc42009dcc0 0xc42009dcd0 0xc42009dce0 0xc42009dcf0 0xc42009dcf1} error: could not parse api creation response, error: json: cannot unmarshal string into Go struct field .hosts of type []*string {"hosts":"hosts is not an array"}

Expected Behavior

Resource created with an empty hosts value

Actual Behavior

Will not actually create it.

Steps to Reproduce

terraform apply

Important Factoids

I am guessing this is happening because Terraform does not appear to be sending the "hosts" value to the plugin, as it is viewing it as empty, or it is supplying it incorrectly.

Crash log

* kong_api.terraform-test-api: unexpected EOF

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform.
A crash log has been placed at "crash.log" relative to your current
working directory. It would be immensely helpful if you could please
report the crash with Terraform[1] so that we can fix this.

When reporting bugs, please include your terraform version. That
information is available on the first line of crash.log. You can also
get it by running 'terraform --version' on the command line.
