ARM Template complex parameters from Runbook Workflow - azure

Question

Have a question about ARM template deployment, specifically calling that deployment from Runbook Powershell workflow using New-AzureRmResourceGroupDeployment cmdlet.
I am trying to use dynamic copy loop in in doing so I am using following formatted parameter in the template:
"aseApAppSettings": {
"type": "object",
"defaultValue": {
"apps": [
{
"name": "app-api-ecom",
"kind": "api"
},
{
"name": "app-ecom",
"kind": "web"
}
]
}
},
Then I create resources based on that:
{
"type": "Microsoft.Web/sites",
"kind": "[parameters('aseApAppSettings').apps[copyIndex()].kind]",
"name": "[concat(parameters('aseApName'),'sv-',parameters('aseApAppSettings').apps[copyIndex()].name)]",
"apiVersion": "2016-08-01",
"location": "East US 2",
"scale": null,
"properties": {...
},
"copy": {
"name": "svLoop",
"count": "[length(parameters('aseApAppSettings').apps)]"
},
"dependsOn": []
},
All works when template is deployed through Template Deployment
I need to call for this deployment from Powershell Workflow runbook and having tough time defining the parameter
I've tried setting it as
{"apps":[{"name":"falcon-api-ecom","kind":"api"},{"name":"falcon-ecom","kind":"web"}]}
during test but it fails with message "Cannot find parameter"
So I have tried using ConvertFrom-Json
But it sends this to my template
"CliXml": "<Objs Version=\"1.1.0.1\"
xmlns=\"http://schemas.microsoft.com/powers...
Please help,
Thanks
Sample from Runbook
workflow Build-Ase {
param
(
#Environment Parameters
[Parameter(Mandatory = $true)]
[object]
$aseApAppSettings
)
$params = #{
"aseApAppSettings" = $aseApAppSettings;
}
$job = New-AzureRmResourceGroupDeployment -ResourceGroupName $vnetRGName -TemplateUri $templateParameterUri -TemplateParameterObject $params
Write-Output $job

Nested objects didn't work for me either, but passing them in as a json string combined with the json function did work for me
Deployment script
$addionalParameters = New-Object -TypeName Hashtable
$addionalParameter1 = "{ ""prop1"": [ { ""name"": ""a"", ""value"": ""1"" }, { ""name"": ""b"", ""value"": ""2"" } ], ""prop2"": { ""name"": ""c"", ""value"": ""3"" } }"
$addionalParameters["myComplexNestedOnjectAsJsonString"] = $addionalParameter1
$deploymentOutput = New-AzResourceGroupDeployment -ResourceGroupName $resourceGroupName -Name $deploymentName -TemplateFile $templateFilePath `
-TemplateParameterFile $parametersFilePath #addionalParameters
Template
{
"parameters": {
"myComplexNestedObjectAsJsonString": {
"type": "string"
}
},
"variables": {
"myComplexNestedObject" : "[json(parameters('myComplexNestedObjectAsJsonString'))]"
},
"resources": [],
"outputs": {
"prop1A": {
"type": "string",
"value": "[variables('myComplexNestedObject').prop1[0].value]"
},
"prop2": {
"type": "string",
"value": "[variables('myComplexNestedObject').prop2.value]"
}
}
}

Try using splatting. For me its the only thing that works with complex nested parameter objects. Also note how the aseApAppSettings parameter is constructed.
$params = #{
$aseApAppSettings = #{ #( {name=...;kind=...},{...},...,{...} ) }
}
New-AzureRmResourceGroupDeployment -ResourceGroupName $vnetRGName -TemplateUri $templateParameterUri #params
ps. ... represent placeholders
