[CTS] API response is not unmarshalled properly

[eonpatapon]

Terraform Version

Terraform v1.1.7
on linux_amd64
+ provider registry.terraform.io/toolbox/flexibleengine v1.28.0

Affected Resource(s)

• flexibleengine_cts_tracker_v1

Terraform Configuration Files

resource "flexibleengine_cts_tracker_v1" "tracker" {
  bucket_name = "xxxx"
  status      = "enabled"
  region      = "eu-west-0"
}

The tracker and bucket was created some time ago. Then plans started to fail with:

Stack trace from the terraform-provider-flexibleengine_v1.25.1 plugin:
panic: runtime error: index out of range [0] with length 0

goroutine 90 [running]:
github.com/terraform-providers/terraform-provider-flexibleengine/flexibleengine.resourceCTSTrackerRead(0xc0004f9480, 0x1454740, 0xc00000c1e0, 0x1eefff0, 0xc000100800)
github.com/terraform-providers/terraform-provider-flexibleengine/flexibleengine/resource_flexibleengine_cts_tracker_v1.go:108 +0x88f

I saw that this was fixed in 1.28.0 via c4e39c8d6ea1183a6eb85fd1174f582055ee65bb, but now with 1.28.0 I get this:

flexibleengine_cts_tracker_v1.tracker: Refreshing state... [id=system]

Error: can not find CTS tracker system

with flexibleengine_cts_tracker_v1.tracker,
on main.tf line 1, in resource "flexibleengine_cts_tracker_v1" "tracker":
resource "flexibleengine_cts_tracker_v1" "tracker" {

Debug Output

Looks like the API response is not what is expected:

@eonpatapon it seems that the API response was changed, can you provide the debug log with API request and response?

the response of Querying a Tracker has two formats:

CTS may support multiple trackers in the future. If the query request GET /v1.0/{project_id}/tracker does not contain parameter tracker_name, the response is in array format. Otherwise, the response is in object format.

@ShiChangkuo here's what I can find:

I believe the call is: [DEBUG] API Request URL: GET https://cts.eu-west-0.prod-cloud-ocb.orange-business.com/v1.0/9f2e36b98a1149aab266626ffbbfXXXX/tracker:

Where 9f2e36b98a1149aab266626ffbbfXXXX is my tenant ID.

@eonpatapon the root reason is the system tracker in error status, I will fixed it asap.
