I’m encountering a System.FormatException when trying to build my all Azure Bicep file into an ARM template JSON.

The command I am using is:

simple.bicep

resource storageAccount 'Microsoft.Storage/storageAccounts@2021-04-01' = {
  name: 'mystorageaccount'
  location: 'West US'
  kind: 'StorageV2'
  sku: {
    name: 'Standard_LRS'
  }
}

bicep build simple.bicep --outfile simple.json

Unhandled exception. System.FormatException: The input string 'dons/microsoft.addons/2017-05-15/types.json#/17' was not in a correct format.

• Bicep CLI version: 0.28.1
• Azure CLI version: 2.62.0
• Operating System: Windows 11 Pro

What could be causing this System.FormatException, and how can I resolve it to successfully build my Bicep file into a JSON ARM template?

Thank you for your help!
