Is Azure Functions down?

Jemali Vashakmadze 20

My Azure Functions was working without problems but all of a sudden it stopped, when I checked there was no functions in my Function App. I tried redeploying but I'm getting "No HTTP triggers found"

Hello @Jemali Vashakmadze,

welcome to this moderated Azure community forum.

The function website itself is up and running...

Are you sure your code still exposes functions?

Can you roll back to a previously working code sample and see if this still deploys ok?

I echo Sander's response @Jemali Vashakmadze. You may have a compile or runtime error that's preventing your trigger functions from being located. Can you use the Diagnose and solve problems blade to help narrow down the issue?

I tried deploying old versions as well and none of them works. My production environment was up and running, haven't even touched it but all of a sudden functions disappeared.

This is what I get when clicking on "Diagnose and solve problems".

I found out what was the issue.

After adding an environment variable, my app restarted.
I have 2 date variables there, having specific format: "2023-10-23T20:30:00.000Z", when app restarts, it changes this variable format for some reason to: "10/23/2023 20:30:00". It was not happening before, after changing the format in my local.settings.json and casting it manually in the code, everything works.

Accepted answer

Glad to hear you were able to resolve your issue @Jemali Vashakmadze. My apologies for not being clear about the list of detectors. Under Availability and Performance, there are a list of detectors that can help provide detail.

From what you've described, sounds like you had a runtime compile error for your function endpoint. An issue like that should have shown up under the Functions that are not triggered or Function App Down or Reporting Errors detectors.

This isn't always the case as it could've also been a deployment error of some kind, in which the detectors under Configuration and Management could be helpful.
