azure - Event subscription by ARM template for topic with EndpointType as AzureFunction

I am trying to create an event grid topic subscription with "endpointType": "AzureFunction". It is giving following error: -

"error": { "code": "InvalidRequest", "message": "Invalid event subscription request: Supplied URL is invalid. It cannot be null or empty and should be a proper HTTPS URL like https://www.example.com." }

My ARM template is given below: -

{
      "name": "[concat(variables('eventGridTopicName'), '/Microsoft.EventGrid/', variables('myFuncName'))]",
      "type": "Microsoft.EventGrid/topics/providers/eventSubscriptions",
      "apiVersion": "2019-01-01",
      "location": "[parameters('location')]",
      "properties": {
        "topic": "[concat('/subscriptions/', parameters('subscriptionId'),'/resourcegroups/', parameters('resourceGroupName'), '/providers/Microsoft.EventGrid/topics/', variables('eventGridTopicName'))]",
        "destination": {
          "endpointType": "AzureFunction",
          "properties": {
            "resourceId": "[resourceId('Microsoft.Web/sites/functions/', variables('funcAppName'), variables('myFuncName'))]",
            "maxEventsPerBatch": 1,
            "preferredBatchSizeInKilobytes": 64
          }
        },
        "filter": {
          "advancedFilters": [
            {
              "operatorType": "StringIn",
              "key": "eventType",
              "values": [
                "xyzEvent"
              ]
            },
            {
              "operatorType": "StringIn",
              "key": "subject",
              "values": [
                "xyzEventReceived"
              ]
            }
          ]
        },
        "labels": [],
        "eventDeliverySchema": "EventGridSchema"
      },
      "dependsOn": [
        "[variables('eventGridTopicName')]"
      ]
    }

Earlier, I was using EndpointType as a webhook since new event handlers like Azure Function, storage Queues, etc. were not available (https://docs.microsoft.com/en-us/azure/event-grid/event-handlers). I used the generated arm template from Azure portal as shown below: -

Has anyone faced this issue?

Yes ! found this when I had same issue! ..

Update! found an example that uses another API version and it seems to work beter, now my issue is that there is no code on it when deploying first time, so I need to break the template into two and deploy content in btween (or deploy content via template ofc).

"apiVersion": "2020-01-01-preview",

https://blog.brooksjc.com/2019/07/19/arm-template-for-event-grid-integration-with-a-new-azure-function/

Update 2, after adding the content and rerunning the template, it work fine!

here is my full code for my storage trigger

{
            "name": "[concat(variables('storageAccountName'), '/Microsoft.EventGrid/coreCostManagementExport')]",
            "type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
            "apiVersion": "2020-01-01-preview",
            "dependsOn": [
                "[resourceId('Microsoft.Storage/storageAccounts',variables('storageAccountName'))]",
                "[resourceId('Microsoft.Web/sites',parameters('functionAppName'))]"
            ],
            "properties": {
                "topic": "[resourceId('Microsoft.Storage/storageAccounts',variables('storageAccountName'))]",
                "destination": {
                    "endpointType": "AzureFunction",
                    "properties": {
                        "resourceId": "[resourceId('Microsoft.Web/sites/functions/', parameters('functionAppName'), 'QueueUsageOnExport')]",
                        "maxEventsPerBatch": 1,
                        "preferredBatchSizeInKilobytes": 64
                    }
                },
                "filter": {
                    "subjectBeginsWith": "/blobServices/default/containers/usage",
                    "subjectEndsWith": ".csv",
                    "includedEventTypes": [
                        "Microsoft.Storage.BlobCreated"
                    ],
                    "advancedFilters": [
                    ]
                },
                "labels": [
                ],
                "eventDeliverySchema": "EventGridSchema"
            }
        }
