Arm template: cannot configure event hub with application gateway diagnostic settings - azure

Question

I have created an Event Hub namespace with event hub and trying to add it into application gateway diagnostic settings but it is not working. (Note: Using nested template)
Here is a working arm template for event-hub:
{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"hapiEnvironmentName": {
"type": "string"
},
"location": {
"type": "string",
"defaultValue": "[resourceGroup().location]"
},
"eventHubSku": {
"type": "string",
"defaultValue": "Standard",
"allowedValues": [ "Basic", "Standard" ]
}
},
"variables": {
"eventHubNamespaceName": "[concat(parameters('hapiEnvironmentName'), 'GatewayWafLogs')]",
"eventHubName": "[concat(parameters('hapiEnvironmentName'), 'AppGWafLogs')]"
},
"resources": [
{
"type": "Microsoft.EventHub/namespaces",
"apiVersion": "2017-04-01",
"name": "[variables('eventHubNamespaceName')]",
"location": "[parameters('location')]",
"sku": {
"name": "[parameters('eventHubSku')]",
"tier": "[parameters('eventHubSku')]",
"capacity": 5
},
"properties": {
"isAutoInflateEnabled": true,
"maximumThroughputUnits": 10
}
},
{
"type": "Microsoft.EventHub/namespaces/eventhubs",
"apiVersion": "2017-04-01",
"name": "[concat(variables('eventHubNamespaceName'), '/', variables('eventHubName'))]",
"location": "[parameters('location')]",
"dependsOn": [
"[resourceId('Microsoft.EventHub/namespaces', variables('eventHubNamespaceName'))]"
],
"properties": {
"messageRetentionInDays": 5,
"partitionCount": 1
}
}
]
}
And here is a piece of application gateway arm template through which I am trying to add Event hub as diagnostic setting.
{
"apiVersion": "2017-05-01-preview",
"type": "Microsoft.Network/applicationGateways/providers/diagnosticSettings",
"name": "[variables('diagnosticSettingsNameForWafLogs')]",
"properties": {
"storageAccountId": null,
"workspaceId": null,
"eventHubAuthorizationRuleId": "/subscriptions/xxx-xxxx-xxxx-xxxxxxx/resourceGroups/xxxxxxxx/providers/Microsoft.EventHub/namespaces/xxxxxxxxx/authorizationrules/RootManageSharedAccessKey",
"eventHubName": "param[('eventhubname')]",
"metrics": [
{
"category": "AllMetrics",
"enabled": false,
"retentionPolicy": {
"enabled": false,
"days": 0
}
}
],
"logs": [
{
"category": "ApplicationGatewayAccessLog",
"enabled": false,
"retentionPolicy": {
"enabled": false,
"days": 0
}
},
{
"category": "ApplicationGatewayFirewallLog",
"enabled": true,
"retentionPolicy": {
"enabled": false,
"days": 0
}
},
{
"category": "ApplicationGatewayPerformanceLog",
"enabled": false,
"retentionPolicy": {
"enabled": false,
"days": 0
}
}
]
},
"dependsOn": [
"[resourceId('Microsoft.Network/applicationGateways', variables('agwafv2Name'))]"
]
}
The error I am getting is:
{
"code": "DeploymentFailed",
"message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.",
"details": [

}
]
}
But the same is working for Log Analytics.

Your template use 2017-05-01-preview api version. In the error message states that this API version is not supported. Does it help if you update api to 2021-03-01.
