Incorrect segment lengths in ARM template - azure

Question

Following Azure Advisory Recommendation, I want to enable diagnostic settings for my app services. I added the following ARM template but keeps getting error:
Deployment template validation failed: 'The template resource 'pr-datap-cf0-config-as/Microsoft.Insights/service' for type 'providers/diagnosticSettings' at line '218' and column '41' has incorrect segment lengths. A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name. Please see https://aka.ms/arm-template/#resources for usage details.'. (Code:InvalidTemplate)
I think my type has 2 segments while name has 3. But what is the type value for diagnosticSettings of an app service?
My ARM template is as follows:
{
"type": "providers/diagnosticSettings",
"apiVersion": "2016-09-01",
"name": "[concat(parameters('appServiceName'), '/Microsoft.Insights/service')]",
"location": "[parameters('location')]",
"dependsOn": [
"[parameters('appServiceName')]"
],
"properties": {
"storageAccountId": "[parameters('diagnosticStorageAccountId')]",
"workspaceId": "[parameters('workspaceId')]",
"metrics": [
{
"category": "AllMetrics",
"enabled": true,
"retentionPolicy": {
"enabled": true,
"days": "[parameters('diagnosticLogsRetentionInDays')]"
}
}
],
"logs": [
{
"category": "AppServiceAuditLogs",
"enabled": true,
"retentionPolicy": {
"enabled": true,
"days": "[parameters('diagnosticLogsRetentionInDays')]"
}
}
]
}

According to my knowledge, there is no type like providers/diagnosticSettings. It should be like Microsoft.Insights/diagnosticSettings or Microsoft.KeyVault/vaults/providers/diagnosticSettings, here are the example templates. And to set the diagnostic setting for the app service, you can take a look at another issue here. And you can also take a look at Enable diagnostics logging for apps in Azure App Service.
