Hi, I have a function app in Python 3.9. This function is deployed to Azure with a DevOps CI/CD pipeline. First, this function app was in Consumption mode. Big downside is that passwords for api calls, etc. are store in the code. We asked Microsoft to get the Flex Consumption Plan, and we get it. Now, I created a second function app, in Flex Consumption Mode. I try to edit the DevOps Release pipeline by changing only the app service name : But now, the release does not work anymore, and sends this error. In red is my App service name, same in the error, in DevOps and in my Azure Portal. (When I switch back to the name of the function in Consumption mode, the deployment works, so it's not a modification I didn't make on purpose that is the cause of this bug.) Searched a long time in forums but I can't find an answer that resolves this issue.

Hi,

I have a function app in Python 3.9. This function is deployed to Azure with a DevOps CI/CD pipeline. First, this function app was in Consumption mode. Big downside is that passwords for api calls, etc. are store in the code.

In red is my App service name, same in the error, in DevOps and in my Azure Portal.

I'm seeing the same in my devops pipelines using the AzureFunctionApp@2 yaml task. Before updating my azure-function-core-tools I got lots of weird errors in the local CLI as well (don't remember if this 404 not found was one of the). after upgrading to 4.0.5801 at least I can publish from CLI.

A workaround might be to create a bash task in the pipeline instead and make sure FA core tools are up to date, and run
func azure functionapp publish <appname>

Thank you for your answer. With it, I can make my original message more clear, with things I forgot to mention.

First, using both 1.* and 2.* task version of Deploy Function App fail with the same error.
Second, deployment via Azure extension in VS Code works. That's why I think the problem comes from something (a setting or I don't know) in build or release pipeline, that differ between Consumption and Flex Consumption

Hi! Please have a look at the considerations for Flex Consumption when in Preview:

Deployments: These deployment-related features aren't currently supported:
