I upgraded my function from net core 3.1 to net 6 in code, then updated function runtime version trough portal to ~4 and net framework version trough following az command
az functionapp config set --net-framework-version v6.0 -n <APP_NAME> -g <RESOURCE_GROUP_NAME>
However when I try to access the app I getting http error 500.
- I tried to look at eventlog.xml and only found IIS AspNetCore Module V2 events about start and stop, no error or exception whatsoever.
- Also I enabled application insight and it shows no requests has being made.
- I restarted, redeployed binaries multiple times
The only alive activity I see is
- Azure respond to OPTIONS with 200
- App host seems running just fine because it shows up a homepage that tells that app is running
- Azure is able to authorize with App Service authentication and set cookie
I understand that I can use debugger because my app still on dev environment but what I'm going to do once I hit this kind of problem on production where developer ways of figuring out the problem is not available and app is just dead in some unusual way?
Update: Forgot to mention that log streaming service shows no incoming requests as well
