I'm sorry the repo is a private repo so I can't share the function code, but this is something was working some time ago, and now my latest builds are getting this error

This doesn't look related to the code. I assume retry also doesnt work? Recommend restarting the app as well in case that helps.

Please share the app name and we will investigate either way. You can use
https://github.com/Azure/azure-functions-host/wiki/Sharing-Your-Function-App-name-privately if needed.

I tried restarting the app, no luck. The name of the app is nocevents

Hi @balag0, This morning, another support eng contacting me the 404 issue happens in UK South (ln1). Yesterday, @divyagandhii just reminded me that the kudulite container never enabled SIGTERM eviction. Could that be an issue where our customers are seeing 404?

[divyagandhisethi]

SIGTERM evictions are completely unrelated to client side 404s.

FWIW, my app was a consumption app. I tried completely re-creating the app, same problem. However I changed the app to a basic plan, instead of consumption based, and now it's working.

I don't know for sure if these things are related or if it was just a coincidence.

[balag0]

Thanks for the additional details. Could you provide the name of the 2nd app you created as well. I am taking a look at this now.

[balag0]

@loganmc10 Found the issue and applied a mitigation. The issue was specific to consumption sku so your experience is not surprising. Could you try again and update please.

There is a small possibility the app you are using might land on a bad worker (not all bad workers are completely drained at this time) but I expect this to be rare. Restarting the app will switch the app to a different worker in case you do hit the issue.

[arjgupta]

@loganmc10 is the issue resolved for you ??

[loganmc10]

Yes, I haven't gone back to the consumption app, but everything is working for me now, and it sounds like the root issue was probably resolved

[loganmc10]

@balag0 I'm running into this again, again with a consumption app:

@loganmc10 Please open a new issue with details on the appname/ timestamps and tag me. Thanks
Will leave this incident closed.
