bigip_ltm_node is adding %1 to node address in the terraform.tfstate file

[blod001]

Environment

• TMOS/Bigip Version: 17.1.1.1
• Terraform Version: v1.6.4
• Terraform bigip provider Version: v1.22.0

Summary

1. I have created a node with the Terraform resource bigip_ltm_node:
   

2. Than I have started a “terraform apply” without any changes, but the Terraform is always claiminig that the ip address is configured with an “%1” at the end and wants to remove the “%1”, which is not possible.
   

The information about the ip with %1 is obviously coming from the F5, so it seems like a kind of a bug ? But in the F5 GUI or CLI the ip address is configured without an “%1”.

We have used the Terraform debug mode and got this information:
2024-05-16T09:09:53.289+0200 [WARN] Provider "provider["registry.terraform.io/f5networks/bigip"]" produced an unexpected new value for module.bigip_ltm_node.bigip_ltm_node.node["node_28"], 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:
- .address: was cty.StringVal("10.70.14.28"), but now cty.StringVal("10.70.14.28%1")

Steps To Reproduce

1. Create a Node with an ip address
2. Run terraform plan / terraform apply

Expected Behavior

After the creation of a node, terraform should not add %1 to the node ip address in the terraform.tfstate file.

Actual Behavior

After the creation of a node, terraform is adding %1 to the node ip address in the terraform.tfstate file.

Hi @blod001,

I tested with version 1.22.1 and there is no error related to %1.

$ terraform plan -out cert 

Terraform used the selected providers to generate the following execution plan.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # bigip_ltm_node.node will be created
  + resource "bigip_ltm_node" "node" {
      + address          = "192.168.30.1"
      + connection_limit = 0
      + description      = "Test-Node"
      + dynamic_ratio    = 1
      + id               = (known after apply)
      + monitor          = "/Common/icmp"
      + name             = "/Common/terraform_node1"
      + rate_limit       = "disabled"
      + ratio            = (known after apply)
      + session          = (known after apply)
      + state            = (known after apply)
    }

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

───────────────────────────────────────────────────────────────────────────────

Saved the plan to: cert

To perform exactly these actions, run the following command to apply:
    terraform apply "cert"


$ terraform apply "cert"
bigip_ltm_node.node: Creating...
bigip_ltm_node.node: Creation complete after 0s [id=/Common/terraform_node1]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.


$ terraform plan -out cert 
bigip_ltm_node.node: Refreshing state... [id=/Common/terraform_node1]

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and
found no differences, so no changes are needed.
