Azure Functions HTTP Trigger not returning expected response with Azure Storage Queue integration
I'm maintaining legacy code that I'm currently developing an Azure Function that is triggered by an HTTP request and subsequently processes messages sent to an Azure Storage Queue... However, I'm facing an issue where the function does not return the expected response, instead, it times out after 30 seconds with a 'Function execution timed out' message. The Azure Function is set to a 1-minute timeout in the host.json, but it seems like the processing logic is causing it to exceed that limit. Here is the relevant part of my Azure Function code: ```csharp [FunctionName("HttpTriggerFunction")] public static async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req, [Queue("myqueue-items", Connection = "AzureWebJobsStorage")] CloudQueue queue, ILogger log) { log.LogInformation("C# HTTP trigger function processed a request."); string requestBody = await new StreamReader(req.Body).ReadToEndAsync(); await queue.AddMessageAsync(new CloudQueueMessage(requestBody)); // Simulate some processing work await Task.Delay(65000); // This simulates a long-running process return new OkObjectResult("Message processed and added to the queue."); } ``` In this code, I am simulating a long-running background process with `Task.Delay()` which I expect to complete before returning a response. I've also checked the Azure Function's host.json settings and it appears to be set correctly: ```json { "version": "2.0", "functionTimeout": "00:01:00" } ``` Despite this, it seems that the HTTP request itself is timing out. I tried breaking down the processing logic into smaller parts and moving it to a separate Azure Function that is invoked by the queue message, but I still receive the same timeout error when hitting the HTTP endpoint directly. I also verified that the Azure Storage connection string is correctly set in the application settings. Is there a limitation on how long an HTTP-triggered Azure Function can take to return a response? What are some best practices for handling long-running processes in this scenario? Any help or insights would be greatly appreciated!
