How to Handle Azure Function Timeout When Calling Long-Running Azure Cognitive Services
I've spent hours debugging this and I need some guidance on I'm a bit lost with I'm writing unit tests and Does anyone know how to I'm following best practices but Quick question that's been bugging me - Quick question that's been bugging me - I'm currently working with a scenario with an Azure Function that invokes Azure Cognitive Services for text analysis. The function often times out after the default execution timeout period of 5 minutes, especially when processing large documents. I understand that Azure Functions can be set to run asynchronously, but when I try to increase the timeout setting in my function app configuration, I still encounter a timeout scenario. Here's my Azure Function code: ```csharp using System; using System.IO; using System.Threading.Tasks; using Microsoft.AspNetCore.Mvc; using Microsoft.Azure.WebJobs; using Microsoft.Azure.WebJobs.Extensions.Http; using Microsoft.AspNetCore.Http; using Microsoft.Extensions.Logging; using Newtonsoft.Json; public static class TextAnalysisFunction { [FunctionName("TextAnalysis")] public static async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req, ILogger log) { log.LogInformation("Processing text analysis request..."); string requestBody = await new StreamReader(req.Body).ReadToEndAsync(); // Assume we have a method to analyze text using Azure Cognitive Services var analysisResult = await AnalyzeTextAsync(requestBody); return new OkObjectResult(analysisResult); } private static async Task<string> AnalyzeTextAsync(string text) { // Simulated call to Azure Cognitive Services that might take a long time await Task.Delay(600000); // Simulates a 10-minute delay return JsonConvert.SerializeObject(new { Result = "Analysis complete" }); } } ``` I've set the timeout in the Azure portal under Function App settings to 10 minutes, but it seems like the function still hits the default timeout. Additionally, I'm using `v3.0` of the Azure Functions runtime. I need some guidance on how to properly extend the timeout or if there are best practices for handling long-running tasks with Azure Functions. Is there a recommended approach to offload this process without hitting the execution time limit? Any insights would be greatly appreciated! Also, I've checked the application settings, and the timeout is definitely set to a higher value: ``` FUNCTIONS_WORKER_RUNTIME = dotnet FUNCTIONS_TIMEOUT = 00:10:00 ``` However, the behavior I receive is: ``` Function 'TextAnalysis' failed with behavior: Timeout ``` Has anyone else encountered this? Am I missing something obvious? Any ideas what could be causing this? I'm working in a Windows 11 environment. Am I missing something obvious? Thanks for taking the time to read this! I'm open to any suggestions. My development environment is Ubuntu 22.04. Thanks in advance!
