Azure Function App - Publish failed

Question

I'm unable to publish (WebDeploy) my Azure Function App (It's a Durable Function, I know it deosn't matter, but, just in case if matters). This started happening today.

I'm getting a "Publish Failed" popup and the below error message in the output window of my Visual Studio.

Error Message

  Publish failed to deploy.

Function Runtime - beta

When I access the Function App Url in a browser I get "Your Function App 2.0 preview is up and running" message". And, I don't see anything wrong in the Kudu portal as well.

I have deleted the Function and re-created it with the same name with no luck.

Any help is much appreciated.

Update : Here is another error that I'm getting as well.

I fixed this issue by setting WEBSITE_RUN_FROM_PACKAGE to 0 on the application settings. I was uploading the function files by syncing a WebDeploy package from Azure DevOps to the App Service file system and not running it from the .zip package.

On https://docs.microsoft.com/bs-cyrl-ba/azure/azure-functions/run-functions-from-deployment-package explains about running Functions from a deployment package and all the benefits of doing it this way, but then remember to:

1. Just upload the .zip deployment package to d:\home\data\sitepackages (don't use the msdeploy verb "sync" to sync the file system at wwwroot)
2. Add a packagename.txt containing only the name of the package file in folder, without any whitespace
