RedisEnterprise resource deployment fails subsequently

[Rasmus715]

Bicep version
Used within Azure DevOps ubuntu-latest agent. 0.38.33 (6bb5d5f)

Describe the bug
When redisEnterpise & database is specified in bicep file, deployment to the Azure fails.
However, manual resource creation via Marketplace works successfully.

To Reproduce

1. Add following resources to bicep file:

resource redisEnterprise 'Microsoft.Cache/redisEnterprise@2025-08-01-preview' = {
  name: 'redis-${prefix}-${environment}-${locationShort}'
  location: location
  sku: {
    name: 'Balanced_B0'
  }
  properties: {
    highAvailability: 'Enabled'
    publicNetworkAccess: 'Enabled'
  }
  tags: {}
}

resource redisEnterpriseDatabase 'Microsoft.Cache/redisEnterprise/databases@2025-08-01-preview' = {
  name: 'default'
  parent: redisEnterprise
  properties: {
    clientProtocol: 'Encrypted'
    evictionPolicy: 'NoEviction'
    clusteringPolicy: 'OSSCluster'
    deferUpgrade: 'NotDeferred'
    persistence: {
      aofEnabled: false
      rdbEnabled: false
    }
    accessKeysAuthentication: 'Enabled'
  }
}

2. Deploy infrastructure to Azure

ARM Template:

        {
            "type": "Microsoft.Cache/redisEnterprise",
            "apiVersion": "2025-08-01-preview",
            "name": "[format('redis-{0}-{1}-{2}', parameters('prefix'), parameters('environment'), parameters('locationShort'))]",
            "location": "[parameters('location')]",
            "tags": {},
            "sku": {
                "name": "Balanced_B0"
            },
            "properties": {
                "highAvailability": "Enabled",
                "publicNetworkAccess": "Enabled"
            }
        },
        {
            "type": "Microsoft.Cache/redisEnterprise/databases",
            "apiVersion": "2025-08-01-preview",
            "name": "[format('{0}/{1}', format('redis-{0}-{1}-{2}', parameters('prefix'), parameters('environment'), parameters('locationShort')), 'default')]",
            "dependsOn": [
                "[resourceId('Microsoft.Cache/redisEnterprise', format('redis-{0}-{1}-{2}', parameters('prefix'), parameters('environment'), parameters('locationShort')))]"
            ],
            "properties": {
                "clientProtocol": "Encrypted",
                "evictionPolicy": "NoEviction",
                "clusteringPolicy": "OSSCluster",
                "deferUpgrade": "NotDeferred",
                "persistence": {
                    "aofEnabled": false,
                    "rdbEnabled": false
                },
                "accessKeysAuthentication": "Enabled"
            }
        },

Additional context
location: WestEurope
Version downgrade of the resource does not mitigate the issue.

It looks like you did not include the "localPath" property to your template. Can you try adding that property and deploy again?

No localPath property is specified in documentation of these resources.

This is an ARM that comes when creating resource via Azure Wizard (Marketplace). It does not contain localPath field as well.

Adding "localPath" to a set of properties of both redisEnterpise and redisEnterpise/database does nothing.
Adding "localPath" to properties of a resource itself fails bicep build.

I'm having same issue as well. It is true that there's no "localPath" configuration based on the documentation.

Any updates? Blocks me from moving to this resource from Azure Cache for Redis

@Rasmus715 if you were already able to deploy these resoures manually, have you tried using the Insert Resource Command or Portal export? Sometimes what happens is the resource provider hasn't correctly documented the available properties - this can help to discover what is missing.

@stephaniezyen I think it would be worth engaging the owners of this resource type internally, to see if they can share guidance on this thread.
