Here is the policy I just created:

{
    "node_type_id": {
        "defaultValue": "Standard_D8s_v3",
        "type": "allowlist",
        "values": [
            "Standard_D8s_v3",
            "Standard_D16s_v3"
        ]
    },
    "num_workers": {
        "hidden": false,
        "type": "fixed",
        "value": 1
    },
    "cluster_type": {
        "hidden": false,
        "type": "fixed",
        "value": "all-purpose"
    },
    "azure_attributes.availability": {
        "type": "fixed",
        "value": "SPOT_WITH_FALLBACK_AZURE",
        "hidden": true
    }
}

Notice a I make the cluster_type value fixed as “all-purpose”. After the policy been created, I continue try to create a job under this policy 

# The main job for asset_bundle_workflow_demo.

resources:
  jobs:
    asset_bundle_workflow_demo_job:
      name: asset_bundle_workflow_demo_job
      schedule:
        
        # Run every day at 8:37 AM
        quartz_cron_expression: '44 37 8 * * ?'
        timezone_id: Europe/Amsterdam

      tasks:
        - task_key: notebook_task
          job_cluster_key: my_job_cluster
          notebook_task:
            notebook_path: ../src/notebook.ipynb

      job_clusters:
        - job_cluster_key: my_job_cluster
          new_cluster:
            policy_id: xxxxxxxxxxxxxxx
            num_workers: 1
            spark_version: 15.4.x-scala2.12
            node_type_id: Standard_D8s_v3
            cluster_type: all-purpose
            azure_attributes:
              availability: SPOT_WITH_FALLBACK_AZURE

And here the error message I got whe try to deploy the asset bundle:

Warning: unknown field: cluster_type

  at resources.jobs.asset_bundle_workflow_demo_job.job_clusters[0].new_cluster

  in resources/asset_bundle_workflow_demo_job.yml:35:13

Error: terraform apply: exit status 1

Error: cannot create job: Cluster validation error: Validation failed for cluster_type, the value must be all-purpose (is "job")

  with databricks_job.asset_bundle_workflow_demo_job,

  on bundle.tf.json line 63, in resource.databricks_job.asset_bundle_workflow_demo_job:

  63:       }

I’m confused because I just set the cluster_type value in the new_cluster section. What is the wrong with my code?
