Trouble with Azure Functions and Durable Functions Orchestrator Timeout Handling
I'm working on an Azure Durable Functions project where I have an orchestrator function that calls an activity function to fetch data from an external API. My orchestrator function is timing out after 5 minutes, even though I can see that the activity function completes successfully. According to the Azure Functions documentation, the maximum timeout for durable orchestrators is set to 1 hour, but I'm encountering a timeout error much sooner. The relevant code for my orchestrator is as follows: ```csharp [FunctionName("OrchestratorFunction")] public static async Task RunOrchestrator([OrchestrationTrigger] IDurableOrchestrationContext context) { var result = await context.CallActivityAsync<string>("ActivityFunction", null); return result; } ``` And my activity function is: ```csharp [FunctionName("ActivityFunction")] public static async Task<string> GetDataFromApi([ActivityTrigger] string name, ILogger log) { using (var client = new HttpClient()) { var response = await client.GetAsync("https://api.example.com/data"); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } ``` I have set the function timeout in the host.json file like this: ```json { "functionTimeout": "00:30:00" } ``` I've also tried setting the `DurableTaskOptions` in the startup class: ```csharp services.AddDurableTask(options => { options.HubName = "DurableFunctionsHub"; options.MaxConcurrentActivityFunctions = 10; }); ``` However, despite these configurations, my orchestrator keeps timing out after about 5 minutes. I've ensured that the Function App is set to the Premium plan to allow longer running functions. Could there be any other setting or configuration that I might be missing? Is there anything specific to durable functions that might be causing the timeout to trigger prematurely? Any insights would be greatly appreciated!
