I am starting my learning for bicep and following the Azure Bicep learning modules. When I was trying out the exercise of (https://learn.microsoft.com/en-gb/learn/modules/build-first-bicep-template/8-exercise-refactor-template-modules?pivots=powershell). It didn't work and threw me an error when I run the command "New-AzResourceGroupDeployment -TemplateFile main.bicep -environmentType nonprod", see error as below:
New-AzResourceGroupDeployment: 10:15:18 PM - Error: Code=InvalidTemplateDeployment; Message=The template deployment 'main' is not valid according to the validation procedure. The tracking id is '4572273f-8839-4ca3-88bb-e092743a4b5f'. See inner errors for details.
New-AzResourceGroupDeployment: 10:15:18 PM - Error: Code=; Message=Object reference not set to an instance of an object.
New-AzResourceGroupDeployment: The deployment validation failed
Before hitting the error, the previous exercise were running fine without any issue. I am sure that I have established the connection successfully via powershell terminal with connect-AzAccount and set the active subscription correctly and I was able to see the subscription, learning resource group information in portal.azure.com/#home and able to see the output of running "Get-azsubscription" from my powershell terminal on my laptop.

It seems your main file has invalid schema or context. Can you share it here?

resource storageAccount 'Microsoft.Storage/storageAccounts@2021-08-01' = {
name: 'toylaunchstorage'
location: 'westus3'
sku: {
name: 'Standard_LRS'
}
kind: 'StorageV2'
properties: {
accessTier: 'Hot'
}
