Required property 'accessTier' not filled in for storage accounts

[StephenWeatherford]

In a bicep file, type:

resource storage 'Microsoft.Storage/storageAccounts@2023-01-01'

and press space-equals => required-properties

It gives you:

resource storage 'Microsoft.Storage/storageAccounts@2023-01-01' = {
  name: 
  location: 
  sku: {
    name: 
  }
  kind: 
}

Fill these in, e.g.

resource storage 'Microsoft.Storage/storageAccounts@2023-01-01' = {
  name: uniqueString(resourceGroup().id, 'afsdhlga')
  location: location
  sku: {
    name: 'Premium_LRS'
  }
  kind: 'BlobStorage'
}

and try to deploy

You get this error:

{
  "code": "InvalidTemplateDeployment",
  "message": "The template deployment 'bicep-deploy' is not valid according to the validation procedure. The tracking id is 'b79122c9-055c-4492-80bd-c1a80c0f792d'. See inner errors for details.",
  "details": [
    {
      "code": "PreflightValidationCheckFailed",
      "message": "Preflight validation failed. Please refer to the details for the specific errors.",
      "details": [
        {
          "code": "MissingRequiredAccountProperty",
          "message": "Account property accessTier is required for the request.",
          "target": "d44py5vkmw72a"
        }
      ]
    }
  ]
}

EXPECTED: Why is there no error in the bicep file if a required property is missing, and why is it not automatically added to the resource?

It's because the swagger spec is not accurate. Transferring to bicep-types-az.
