v4 functions are not being found in portal, local works

[Venipa]

After deploying through azure devops pipeline with zip deploy and run there were no functions to be found on our productive and beta function app but somehow our dev function app is able to find them?

also locally the functions are loaded and working well

Investigative information

Please provide the following:
unable to get function invocation, no logs

functions are placed like this in dist
src/functions/[function name]/index.ts => dist/src/functions/[function name]/index.js

Expected behavior

expected my functions to be found

Actual behavior

dev azure functions app found all functions, pre production & production environment are unable to find the function

Known workarounds

none

Hi @Venipa can you please share your function app name? Here are instructions on how to do it privately if you don't want to post it publicly: https://github.com/Azure/azure-functions-host/wiki/Sharing-Your-Function-App-name-privately

Hi I'm seeing this error when starting up your app:

E_INVALID_APP_KEY: Invalid App Secret

I would double check all your app settings and make sure they're valid.

In addition, if you query your app insights logs, I believe this error should be visible:

let myAppName = "api-timeghost-beta";
let startTime = ago(1d);
let endTime = now();
union traces,requests,exceptions
| where cloud_RoleName =~ myAppName
| where timestamp between (startTime .. endTime)
| where severityLevel > 2

thanks, since my log stream was not working i was unable to get any logs about the startup, i was missing a env variable providing a app secret for encrypting payloads

functions are being listed now, thanks 👍
