Examples

The following code raises the diagnostic code because the resource name isn't valid according to Azure rules - the -(dash) character isn't permitted. For more information, see Resource name rules.

param location string = resourceGroup().location

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

You can fix the issue by correcting the resource name property value to meet the naming requirements:

param location string = resourceGroup().location

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