Deploy Python Function to Azure Function App failed

[silvermoong]

Repro steps:
I'm using the auto generated Python HTTP triggered function and I'm able to debug and run it locally(with localhost url).

I firstly tried to deploy my function to my existing Function App (It has no function in it) on Azure. The deployment succeeded and I can see the new function be added into the Function App. But I got 404 when I clicked run or enter the function URL in my browser.

I then did the second deployment by creating a new Function App and Storage Account in Central US. This time I'm getting "Requested features are not supported in region." error.

When I browse the resources, I can see the Resource Group and Storage Account are created, but the Function App is not.

Action: azureFunctions.deploy
Error type: BadRequest
Error Message: Requested features are not supported in region.

Version: 0.11.0
OS: win32

Yes that error message is expected for Linux Consumption function apps (the only type that supports Python). Right now we show all regions, but we have an existing issue to filter out the regions that don't support it: #641

I'm more interested in your 404 error. Do you see the function listed in the explorer? Was this an anonymous http trigger? Or did it have auth?

Hello Eric,

Thanks for the explanation.

The 404 error is happening on a Function App that I create through portal UI. I don't remember how did I set it up, but this is definitely not a Linux Function App. So I guess this could be the issue.

I deployed my python function form VS Code to the Function App. I can see it listed in the Function App. I can't run it nor access from the Function URL. It is an anonymous http trigger.

Here's a wiki on the preview support for Python: https://github.com/Azure/Azure-Functions/wiki/Azure-Functions-on-Linux-Preview

If you deploy through VS Code and create a new function app - make sure to use one of these regions (copied from the doc above):

• West US
• East US
• West Europe
• East Asia

Hello Eric,

It works after I create the Function App from VS Code and located in East US.

Thanks for the solution

Awesome! I know this isn't the most obvious set of steps, but we already have a few issues to track improvements (#619 #641), so I'll go ahead and close this issue.
