Azure Function App Only Runs When I Open the Azure Portal

Question

I have recently Created an Azure PowerShell Function from the portal. The function is setup to trigger every day at 4 PM. This works fine when I am logged in to the Portal but when In active in or if my laptop is shutdown, it does not trigger.

Below is the function.json,

{
  "bindings": [
    {
      "name": "Timer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 0 16 * * *"
    }
  ]
}

Any help highly appreciated.

Thanks,

Hi Mohammed Sohel Thanks for reaching out. One of the first things I'd recommend is to check is runOnStartup and make sure that is set to false.

This issue can happen if your Azure function is on consumption plan.

To ensure that your Azure Function runs continuously and triggers at the scheduled time, you can switch to the App Service plan and configure the function app to run continuously. The App Service plan provides dedicated resources for your function app and allows you to run your function app continuously.

Note: Please set Alwayson option ON under configuration blade.

If you have any further query do let us know. I would be happy to help.
