Wants to update "ssh_key_path" although not configured / not changed

[larsen0815]

Description

I have imported a datacenter and server. Adapted the main.tf to resemble the current state. When I run "terraform plan", I get this:

  # ionoscloud_server.Vermont will be updated in-place
  ~ resource "ionoscloud_server" "Vermont" {
        id                = "123-456"
        name              = "Vermont Server"
      + ssh_key_path      = (known after apply)
        # (9 unchanged attributes hidden)

        # (3 unchanged blocks hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.

It's null in terraform.tfstate:

# grep ssh_key_path terraform.tfstate
            "ssh_key_path": null,
                "ssh_key_path": []

When I change main.tf to include "ssh_key_path = null", terraform still wants to set "ssh_key_path".

Expected behavior

I'm not sure if this is already the expected behaviour, but I think the ionoscloud provider shouldn't want to change "ssh_key_path".

Terraform v1.0.0
on linux_amd64
