Azure Functions Timeout Issue When Triggered by Azure Event Grid Notifications
I'm dealing with I'm dealing with I'm trying to figure out I'm relatively new to this, so bear with me. After trying multiple solutions online, I still can't figure this out. I'm experiencing a timeout issue with my Azure Functions that are triggered by Azure Event Grid notifications. My function is set to process messages coming from an Azure Blob Storage event when a file is created. However, it seems to consistently hit the timeout limit of 5 minutes, even though the processing logic should complete much faster. Here’s the code snippet for my function: ```csharp using System; using System.IO; using Microsoft.Azure.WebJobs; using Microsoft.Extensions.Logging; public static class BlobTriggerFunction { [FunctionName("BlobTriggerFunction")] public static void Run([BlobTrigger("uploads/{name}")] Stream blobStream, string name, ILogger log) { log.LogInformation($"Processing blob Name:{name} Size: {blobStream.Length} Bytes"); // Simulate processing System.Threading.Thread.Sleep(600000); // Simulating long processing time } } ``` I've tried increasing the timeout duration in the host.json file, but it seems to have no effect: ```json { "functionTimeout": "00:10:00" } ``` Additionally, I verified that the Azure Function plan is set to "Premium" so that I can enable longer execution times. However, I still see the following error in the logs: `Function 'BlobTriggerFunction' failed: Timeout exceeded.` I suspect that the processing simulated by `Thread.Sleep` is causing issues, but I need to ensure that my function can handle long-running tasks without timing out. What would be the best approach to handle this scenario, and how can I avoid the timeout issue while still processing the blob data effectively? This is part of a larger service I'm building. Has anyone else encountered this? This is part of a larger application I'm building. I'd really appreciate any guidance on this. This issue appeared after updating to Csharp stable. Thanks, I really appreciate it! Could this be a known issue? I'm on Ubuntu 22.04 using the latest version of Csharp.
