Bicep diagnostic code - BCP029

2025-10-15

This diagnostic occurs when you specify an invalid format of a resource type.

Description

The resource type isn't valid. Specify a valid resource type of format <types>@<apiVersion>.

Level

Error

Solution

Use the valid format of resource type.

Examples

The following example raises the diagnostic because the Microsoft.Storage/storageAccounts resource type requires an API version:

param location string = resourceGroup().location

resource storage 'Microsoft.Storage/storageAccounts' = {
  name: 'mystorageacct'
  location: location
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'StorageV2'
}

You can fix the diagnostic by providing an API version:

param location string = resourceGroup().location

resource storage 'Microsoft.Storage/storageAccounts@2025-01-01' = {
  name: 'mystorageacct'
  location: location
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'StorageV2'
}
