[DXE-3690] API Match Target wants to update on every terraform plan

[martinrw]

Terraform Version

v1.3.4

terraform {
  required_providers {
    akamai = {
      source  = "akamai/akamai"
      version = "5.5.0"
    }
  }
}

Affected Resource(s)

• akamai_appsec_match_target
  But seems like only for API type targets

Terraform Configuration Files

resource "akamai_appsec_match_target" "myservice_match_target" {
  config_id    = data.akamai_appsec_configuration.mycompany_config.config_id
  match_target = templatefile("${path.module}/appsec/api_match_targets.json", {
    config_id           = data.akamai_appsec_configuration.mycompany_config.config_id,
    myservice_hostname  = var.myservice_hostname
    security_policy_id  = akamai_appsec_security_policy.my_security_policy.security_policy_id
  })
}

And the Matchtargets Json file:

{
    "type": "api",
    "configId": "${config_id}",
    "defaultFile": "NO_MATCH",
    "effectiveSecurityControls": {
        "applyApplicationLayerControls": true,
        "applyBotmanControls": true,
        "applyNetworkLayerControls": true,
        "applyPageIntegrityControls": false,
        "applyRateControls": true,
        "applyReputationControls": true,
        "applySlowPostControls": true
    },
    "filePaths": [
      "/*"
    ],
    "hostnames": [
      "${myservice_hostname}"
    ],
    "isNegativeFileExtensionMatch": false,
    "isNegativePathMatch": false,
    "securityPolicy": {
      "policyId": "${security_policy_id}"
    },
    "apis": [
      {
        "id" : 12345,
        "name" : "myservice-Akamai-Test"
      }
    ]
  }

Actual Behavior

The terraform plan wants to remove the "targetid" field every time. Even after I apply it and run the plan again it still wants to remove it:

  # module.akamai.akamai_appsec_match_target.myservice_match_target will be updated in-place
  ~ resource "akamai_appsec_match_target" "myservice_match_target" {
        id              = "67890:7658471"
      ~ match_target    = jsonencode(
          ~ {
              + configId                     = "67890"
              + defaultFile                  = "NO_MATCH"
              + effectiveSecurityControls    = {
                  + applyApplicationLayerControls = true
                  + applyBotmanControls           = true
                  + applyNetworkLayerControls     = true
                  + applyPageIntegrityControls    = false
                  + applyRateControls             = true
                  + applyReputationControls       = true
                  + applySlowPostControls         = true
                }
              + filePaths                    = [
                  + "/*",
                ]
              + hostnames                    = [
                  + "myservice-akamai-test.mycompany.eu",
                ]
              + isNegativeFileExtensionMatch = false
              + isNegativePathMatch          = false
              - targetId                     = 7658471 -> null
                # (3 unchanged elements hidden)
            }
        )
        # (2 unchanged attributes hidden)
    }

Expected Behavior

The plan should show no differences, there should be nothing to change.
My understanding is that the targetid is a unique ID for the match target so I don't see how I can pre-populate that in the matchtarget json file.

I have another match target why is type website and it doesn't seem to do the same thing
