Azure Timer Function Not Firing Automatically

Demitra Del Fiacco 21 Reputation points

I have a function app on an app service plan (S1 tier). In this function app I have a singular timer function. However, the function is not firing automatically based on the CRON expression I have provided. I am able to run the function manually, but it will not fire by itself.

Here is my function.json:
"bindings": [
"name": "myTimer",
"type": "timerTrigger",
"direction": "in",
"schedule": "0 50 11 * * WED"

Can someone please let me know if there is anything I am missing to make this function run automatically?

    Hi @Demitra Del Fiacco ,

    Please make sure the "Always on" setting is turned on under the configuration settings.

    This setting would keep the app active even when there's no traffic. It's required for continuous WebJobs or for functions that are triggered using a CRON expression.

    I hope this helps!

    It doesn't look like your CRON expression is correct (at least 5 parts are required). What's your requirement on the CRON expression?

    My cron definition is 0 star star star star star, so every minute. But the stars are rendered incorrectly on this webpage.
