I have a 'grandparent' master template that deploys another linked 'parent' template 4 times, each time with different group name (I've only shown the first resource):
{
"$schema": "https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"resourcegroupName": {
"type": "string",
"metadata": {
"description": "The name given to the group and all resources it contains by default"
}
},
"resourceGroupLocation": {
"type": "string",
"metadata": {
"description": "The Location of the resource group"
}
},
"templateFolderUri": {
"type": "string",
"metadata": {
"description": "The URI of the template component folder"
}
}
},
"functions": [],
"variables": {},
"resources": [
{
"name": "[concat(parameters('resourceGroupName'), 'Dev')]",
"type": "Microsoft.Resources/deployments",
"apiVersion": "2021-04-01",
"location": "[parameters('resourceGroupLocation')]",
"properties": {
"mode": "Incremental",
"templateLink": {

"resourcegroupName": "[concat(parameters('resourcegroupName'), 'Dev')]",
"resourceGroupLocation": "[parameters('resourceGroupLocation')]",
"templateFolderUri": "[concat(parameters('resourcegroupName'), '/Components')]"
}
}
},
<resource repeated 3 times>
],
"outputs": {}
}
The 'parent' template, also links other 'child' templates and looks like so:
{

}
},

"type": "string",
"metadata": {
"description": "The Location of the resource group"
}
},
"templateFolderUri": {
"type": "string",
"metadata": {
"description": "The URI of the template component folder"
}
}
},
"functions": [],
"variables": {},
"resources": [

"properties": {}
},
{

"contentVersion": "1.0.0.0"
}
},
"dependsOn": [
"[resourceId('Microsoft.Resources/resourceGroups/', parameters('resourceGroupName'))]"
]
},
{
"name": "[concat(parameters('resourceGroupName'), 'Storage')]",

},
{

"[resourceId('Microsoft.Resources/deployments', parameters('resourceGroupName'))]"

}
],

}
The 'parent' template works when ran on its own, the parent template does not. I get an error for the type of each resource in the grandparent template:
##[error]Multiple error occurred: BadRequest,BadRequest,BadRequest,BadRequest. Please see details.

I believe I understand why this is happening as in the 'grandparent' template I am linking the 'parent' as "type": "Microsoft.Resources/deployments" when the 'parent' template deploys a resource group and operates on the subscription scope. I also tried setting the type to "type": "Microsoft.Resources/resourceGroups" but that also did not work. I believe this can be fixed by moving the resource group from the 'parent' template to the 'grandparent' but I am wondering if there is a resource type that can more easily accommodate both these types in the same linked template.
When passing parameters to the linked templates, the parameters need an additional property added called "value": ....
Fixing a portion of the example provided, the result would look like
...
"parameters": {
"resourcegroupName": {
"value": "[concat(parameters('resourcegroupName'), 'Dev')]"
},
"resourceGroupLocation": {
"value": "[parameters('resourceGroupLocation')]"
},
"templateFolderUri": {
"value": "[concat(parameters('templateFolderUri'), '/Components')]"
}
}
...
