what if reporting small subset of resources which would actually be created

[maniSbindra]

Describe the bug
Executing az deployment what-if reports that only 2 resources will be created, when actually more than 10 resources are created when you actually deploy. The https://github.com/Azure-Samples/avm-bicep-labs/tree/main/labs/lab02 sample has been used. I have seen similar behaviour for other ARM template and bicep files

To Reproduce
Steps to reproduce the behavior:

1. Clone the repo git clone https://github.com/Azure-Samples/avm-bicep-labs/tree/main/labs/lab02
2. az login to your subscription
3. az deployment sub what-if --name test-dep-sub-scope-1 --template-file "avm-bicep-labs/labs/lab02/main.bicep" -p @avm-bicep-labs/labs/lab02/main.parameters.json -l westeurope
   Result of above command is

$ az deployment sub what-if --name test-dep-sub-scope-1 --template-file "avm-bicep-labs/labs/lab02/main.bicep" -p @avm-bicep-labs/labs/lab02/main.parameters.json -l westeurope                                                  

Note: The result may contain false positive predictions (noise).

Resource and property changes are indicated with this symbol:

The deployment will update the following scopes

Resource changes: 2 to create.

Actual behaviour

As described above what-if analysis shows only 2 resources would be created

$ az deployment sub what-if --name test-dep-sub-scope-1 --template-file "avm-bicep-labs/labs/lab02/main.bicep" -p @avm-bicep-labs/labs/lab02/main.parameters.json -l westeurope

Resource changes: 2 to create.

Expected behavior
As you can see from the bicep file and the lab02 description and Architecture over 10 resource should actually be created . I validated this by deploying the bicep code. I also manually tried generating the ARM from bicep and executing that, and saw the same behaviou1

Screenshots

Client [e.g. PowerShell, CLI, API)

• I am using a M1 Mac
• az cli version : 2.71.0
