Internal server error returning integer from v2 function app

Question

I am getting internal server errors when returning data from a v2 Azure function (.Net Core). I have reduced it to a very simple case:

   [FunctionName("invoke")]
    public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = null)] HttpRequest req, ExecutionContext context)
    {
        try
        {

            var obj = new OkObjectResult(10);
            return obj;
        }
        catch (Exception e)
        {
            return new BadRequestObjectResult(e.ToString());
        }
    }

Strangely it happens on two of my subscriptions and not the third

Hi @George Aggrey

Thanks for your time reaching offline.
As discussed, you have confirmed that the issue is resolved and found that as you were deploying function using Terraform then in that case you should not set FUNCTIONS_EXTENSION_VERSION instead set azurerm_function_app.version

Updating the FUNCTIONS_EXTENSION_VERSION to "2.0.15229.0" helps you to resolve the issue.
