After migration to .NET 8 Isolated, unable to publish using Visual Studio 2022

Question

Hi,

I upgraded an Azure Function (Linux) to dotnet 8 Isolated model following the documentation.

The function runs fine in local, but I cannot publish it to Azure. I get the error "The attempt to publish the ZIP file through https://<fctappurl>.scm.azurewebsites.net/api/zipdeploy failed with HTTP status code Failed."

The logs are very helpful : "we were unable to determine the root cause of the error"...

Any help appreciated.

Answer 1

I struggled with this error "failed with HTTP status code Failed." for hours. Upgraded Frameworks, tools, etc. Eventually I tried creating a different type of Azure Function, which then gave me a quota error, as our admin had limited the regions into which we can deploy. I changed it to the 'approved' region, and it worked fine. I then recreated the function as Flex Consumption selecting the same region, and the deploy worked without issue.

Hopefully this helps someone struggling with the "HTTP status code Failed" issue.

Answer 2

After a day of searching around, I have just installed the latest version of Visual Studio (17.12.4) and it does support Azure Functions Flex Consumption.

Thats a good thing for me, I deploy the same app into QA, Staging and Production, so I can use the same publish and config settings as I do in my other projects (vscode is different in this respect and I didn't fully work out how to do it).

Answer 3

At time to add this answer I have the same error to publish my functions (Azure Function on Linux with dotnet 8 Isolated). Aparently this is a problem with Visual Studio 2022 that not suport this publish method, but you can use Visual Studio Code with Azure Functions extension. Process is relativately simple: install extension, log in your Azure account in VS Code, search your Azure Function resource, left click and Publish.
