I have written an ARM template to create an event subscription on an existing storage account, where I need to listen to a particular blob container's blob.created and blob.deleted events, and send them to an Azure eventgrid trigger function app.
The functionapp is already deployed in Azure https://myfunctionapp.azurewebsites.net, and I am having a hard time trying to create the event subscription through the ARM template. Please note that I have used API version 2020-01-01-preview in order to have AzureFunction as the endpoint. The template is as follows:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"appName": {
"type": "string",
"metadata": {
"description": "Name of the function app"
}
},
"functionName": {
"type": "string",
"defaultValue": "MyFunction",
"metadata": {
"description": "Name of the function"
}
},
"eventSubName": {
"type": "string",
"defaultValue": "myfunctionappsub",
"metadata": {
"description": "The name of the event subscription to create."
}
},
"storageName": {
"type": "string",
"metadata": {
"description": "Storage account name"
}
},
"location": {
"type": "string",
"defaultValue": "[resourceGroup().location]",
"metadata": {
"description": "Storage account location"
}
},
"containerNamefilter": {
"type": "string",
"defaultValue": "-inputblob",
"metadata": {
"description": "Container name filter"
}
}
},
"variables": {
"functionAppName": "[resourceId('Microsoft.Web/sites/functions/', parameters('appName'), parameters('functionName'))]"
},
"resources": [
{
"type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
"name": "[concat(parameters('storageName'), '/Microsoft.EventGrid/', parameters('eventSubName'))]",
"apiVersion": "2020-01-01-preview",
"dependsOn": [
"[parameters('storageName')]"
],
"properties": {
"destination": {
"endpointType": "AzureFunction",
"properties": {
"resourceId": "[variables('functionAppName')]"
}
},
"filter": {
"subjectBeginsWith": "",
"subjectEndsWith": "",
"isSubjectCaseSensitive": false,
"includedEventTypes": [
"Microsoft.Storage.BlobCreated",
"Microsoft.Storage.BlobDeleted"
],
"advancedFilters": [
{
"key": "subject",
"operatorType": "StringContains",
"value": "[parameters('containerfilter')]"
}
]
}
}
}
]
}
This is the error I get when I try to run it on the pipeline:

Am I doing anything wrong here? I'm very new to ARM templates.
