ResourceDeploymentFailure error while automating Event Grid

Question

I am working on automating event grid subscription through ARM templates. We are using EventGridTrigger in Azure Functions V2. I have tried below two approaches and getting the same error for both of the approaches:

{
    "name": "[parameters('topicName')]",
    "type": "Microsoft.EventGrid/topics",
     "location": "[parameters('location')]",
     "apiVersion": "2018-01-01",
     "resources": [
       {
         "apiVersion": "2018-01-01",
         "name": "[concat(parameters('topicName'), '/Microsoft.EventGrid/', parameters('subscriptionName'))]",
         "type": "Microsoft.EventGrid/topics/providers/eventSubscriptions",
         "dependsOn": [
           "[parameters('topicName')]"
         ],
         "properties": {
           "destination": {
             "endpointType": "WebHook",
             "properties": {
               "endpointUrl": "[listsecrets(resourceId(parameters('resourceGroupName'), 'Microsoft.Web/sites/functions', parameters('functionAppName'), 'FunctionName'),'2015-08-01').trigger_url]"
             }
           },
           "filter": {
             "includedEventTypes": [
               "EventType"
             ]
           }
         }
}]}

In the second approach, I used endpointUrl: [concat('https://', parameters('functionAppName'),'.azurewebsites.net/api/FunctionName?code=', listKeys(concat(variables('functionAppId'), '/functions/FunctionName'),'2016-08-01').default)]

Getting below error:

{
    "status": "Failed",
    "error": {
        "code": "ResourceDeploymentFailure",
        "message": "The resource operation completed with terminal provisioning state 'Failed'.",
        "details": [
            {
                "code": "Url validation",
                "message": "The attempt to validate the provided endpoint https://<functionAppName>.azurewebsites.net/api/FunctionName failed. For more details, visit https://aka.ms/esvalidation."
            }
        ]
    }
}

Has anyone done automation using latest SDKs?
