[BUG] ARM template appears to be modified erroneously by the SDK

Describe the bug

One of the parameters provided in the ARM deployment template appears to be modified incorrectly by the Azure SDK. I’m upgrading the SDK in our system from version 1.18.0 to 1.32.1 and it was working fine on version 1.18.0.

Parameter in the template before submitting deployment request:

{
    "properties": {
        "template": {
            "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
            "contentVersion": "1.0.0.0",
            "parameters": {
                ...
                ...
                "sfcUserAssignedIdentities": {
                    "type": "object",
                    "defaultValue": {
                        "/subscriptions/<redacted>/resourceGroups/<redacted>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<redacted>": {}
                        }
                    }
                },

Parameter after submitting the deployment request. The resource Id is broken down into a json fragment. I captured this by adding a logging interceptor on the client side and also observed the same through deployment history on Azure portal.

{
    "properties": {
        "template": {
            "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
            "contentVersion": "1.0.0.0",
            "parameters": {
                ...
                ...
                "sfcUserAssignedIdentities": {
                    "type": "object",
                    "defaultValue": {
                        "/subscriptions/<redacted>/resourceGroups/<redacted>/providers/Microsoft": {
                            "ManagedIdentity/userAssignedIdentities/<redacted>": {}
                        }
                    }
                },

Code for submitting deployment request:

azure.deployments().define(deplName)
     .withExistingResourceGroup(rgName)
     .withTemplate(templateJson)
     .withParameters("{}")
     .withMode(DeploymentMode.INCREMENTAL)
     .beginCreate();

Dependency not fixed. Mitigated in SDK. To be released for 1.34.0, around 1st May.

@SukruthKS Good to know the workaround works.

I will continue work with owner of the dependency lib on the fix to root cause. If things work as expected, next release (1.34.0, scheduled on 1st May) should have it fixed.
