what-if operation doesn't seem to include all bicep defined or created resources

[anthonyfourie]

Bicep version
run bicep --version via the Bicep CLI, az bicep version via the AZ CLI or via VS code by navigating to the extensions tab and searching for Bicep
"azure-cli": "2.26.0"
"azure-cli-core": "2.26.0"
"azure-cli-telemetry": "1.0.6"
Bicep CLI version 0.4.412 (f1169d0)

Describe the bug
A clear and concise description of what the bug is vs what you expected to happen
The output for the what-if operation doesn't include all resources defined in the bicep template.
The deployment of all resources defined in the template succeeds, just not all show up in the what-if output.

To Reproduce
Steps to reproduce the behavior:
Extract the attached Bicep files to deploy Azure resources using the CLI.
Login to Azure with:
az login

Then issue a what-if deployment operation for a subscription level deployment:
az deployment sub what-if --name 'deploymentName' --location 'region' --template-file '.\src\bicep\deployAnalyticsPlatform.bicep'

Also tried the --no-pretty-print option:
az deployment sub what-if --name 'deploymentName' --location 'region' --template-file '.\src\bicep\deployAnalyticsPlatform.bicep' --no-pretty-print

or using:
az deployment sub --name 'deploymentName' --location 'region' --template-file '.\src\bicep\deployAnalyticsPlatform.bicep' --confirm-with-what-if

The scope, storage account, blob container resources are output but not the Azure Synapse Workspace resource:

The source files:
src.zip

Are you passing in a module output or resource property into the module as a param? If so, this is most likely an instance of Azure/arm-template-whatif#157

[anthonyfourie]

Hey @alex-frankel, yes. I pass the outputs from the storage module to the synapse module:

I did a quick test to confirm if I supplied the string literal instead of the outputs then the resources appear in the what-if output.

Seems it is an instance of Azure/arm-template-whatif#157

Cool - I'm going to close this as a dup. Hopefully we can get this resolved soon!
