Debug Output/Panic Output

[WARN] Provider "registry.terraform.io/opentelekomcloud/opentelekomcloud" produced an invalid plan for module.ecs2.opentelekomcloud_compute_volume_attach_v2.volume_attach["data2"], but we are tolerating it because it is using the legacy plugin SDK. The following problems may be the cause of any confusing errors from downstream operations:

.device: planned value cty.UnknownVal(cty.String) does not match config value cty.StringVal("/dev/vdb")

Steps to Reproduce

Try to attach an EVS to ECS, with path (device)

Expected Behavior

I expected that it will attached the EVS volume to the proper path to the ECS

Actual Behavior

Randomly attached the EVS disks
