Describe the bug
Description of issue you're seeing...

From another issue #2012
azd checks api/deployment/latest for deployment to function apps. This works consistently when you use a premium plan, but occasionally fails when deploying to a linux consumption plan with the following error:

 azd deploy

Deploying services (azd deploy)

  (x) Failed: Deploying service api

ERROR: failed deploying service 'api': failing invoking action 'deploy', GET https://func-api-yvxujhed7pxw4.scm.azurewebsites.net:443/api/deployments/latest
--------------------------------------------------------------------------------
RESPONSE 404: 404 Not Found
ERROR CODE UNAVAILABLE
--------------------------------------------------------------------------------
Deployment 'latest' not found.
--------------------------------------------------------------------------------

TraceID: 1799bd90c56c4cf4fdc799e3b65b2cd2

To Reproduce
Steps to reproduce the behavior...

Run azd deploy with any function on a linux consumption plan. Service should be defined in azure.yaml like the following:

services:
  api:
    project: ./api/functions
    language: python
    host: function

Expected behavior
A clear and concise description of what you expected to happen.

azd deploy works consistently regardless of the underlying app service plan

Environment
Information on your environment:
* Language name and version
* IDE and version : [e.g. Visual Studio 16.3]

python, vscode

@mattgotteiner Outside of differences between premium vs consumption plan are there any other notable differences on the function app configuration around networking, etc?

Are you experiencing the same consumption app behaving different and occasionally failing? Is this a semi-consistent experience always or is it most likely to occur on the first deploy to the function app?

[mattgotteiner]

1. No, no notable differences
2. Deployment occasionally fails. Most likely to occur on first deploy, but may happen again on a re-deploy

[mattgotteiner]

More info: This seems to only happen when I include large files in the deployment. This might be a service issue and unrelated to azd

[brandonh-msft]

I'm having issues getting a .NET Consumption plan Function to deploy correctly at all. Struggled for an entire day yesterday to make this work.

I deployed fine via func azure functionapp publish after creating the infra w/ azd, but azd's deploy results in a broken app every time.

If we could publish a sample that actually works w/ Consumption plan Zip Deploy on Linux that'd be great.

[weikanglim]

@brandonh-msft This Linux Flex Consumption plan sample is being published as we speak: https://github.com/Azure-Samples/functions-quickstart-dotnet-azd-timer/

I just tested this locally and it does seem to be working, curious to hear if this could help get you further along.
