Azure Functions: Timeout implementing Durable Task Orchestrator in V3 Runtime
I need help solving I'm converting an old project and I'm having a hard time understanding I tried several approaches but none seem to work... Hey everyone, I'm running into an issue that's driving me crazy. I am working with a timeout scenario while using Durable Functions in Azure Functions V3. I have an orchestrator function that calls several activity functions, and I am seeing unexpected behavior where the orchestrator times out even though the execution should be well within the allowed limits. Here's a snippet of my orchestrator function: ```csharp [FunctionName("MyOrchestrator")] public static async Task<string> RunOrchestrator( [OrchestrationTrigger] IDurableOrchestrationContext context) { var result1 = await context.CallActivityAsync<string>("ActivityFunction1", null); var result2 = await context.CallActivityAsync<string>("ActivityFunction2", result1); return result2; } ``` The activity functions are fairly lightweight, but I've noticed that sometimes the orchestrator can take longer than expected, especially when there are more than a couple of parallel calls. I have set the `FUNCTIONS_WORKER_RUNTIME` to `dotnet` and my Azure Functions version is V3. Despite configuring the timeout to be a bit longer using the Durable Task Settings in `host.json`, I still encounter the `Function 'MyOrchestrator' failed to run: Timeout exceeded` behavior intermittently. Here’s the relevant part of my `host.json`: ```json { "durableTask": { "extendedSession": true, "maxConcurrentActivityFunctions": 10, "maxConcurrentOrchestratorFunctions": 5, "functionTimeout": "00:10:00" } } ``` I have tried increasing the timeout in the `host.json`, but it doesn’t seem to resolve the scenario. Also, I have verified that the Azure Functions app is not exceeding the consumption plan limits. Any insights on what might be going wrong or how I can further diagnose this scenario? Are there any best practices I should follow while working with Durable Functions to avoid such timeouts? How would you solve this? For reference, this is a production CLI tool. What's the correct way to implement this? I'm working on a mobile app that needs to handle this. Am I missing something obvious? Any ideas what could be causing this? Is there a better approach?
