Azure DevOps - Deployment problems - azure

Question

I am trying to deploy a new code in an existing function on Azure but for some reason I am getting a Green/Pass pipeline but when I request the URL I got error 404.
What I have done:
Setup the function manually
Run a Pipeline with the stages:
a) mvn package
b) zip content of azure functions in the target
c) Deploy artifact from agent to the pipeline
d) Deploy artifact into a function using snipped code from microsoft.
The pipeline gets a green state and the function has been deployed:
Starting: AzureFunctionApp
==============================================================================
Task : Azure Functions
Description : Update a function app with .NET, Python, JavaScript, PowerShell, Java based web applications
Version : 1.195.0

Got service connection details for Azure App Service:'test'
Trying to update App Service Application settings. Data: {"WEBSITE_RUN_FROM_PACKAGE":"https://teststorage.blob.core.windows.net/azure-pipelines-deploy/package_1639741028399.zip?***"}
Updated App Service Application settings.
Updated WEBSITE_RUN_FROM_PACKAGE Application setting to https://teststorage.blob.core.windows.net/azure-pipelines-deploy/package_1639743928399.zip?***
Syncing triggers for function app
Sync triggers for function app completed successfully
Successfully added release annotation to the Application Insight :test
App Service Application URL: http://test.azurewebsites.net
Finishing: AzureFunctionApp
but when I request the URL it fails, also I check the functions section in the portal , and the function that was there (deployed manually) got removed.
Note:
The code is fine because I can deploy manually the same code and it is working fine, via pipeline is not working.
Pipeline code:

Answer 1

rootFolderorFile - Enter the root folder or file path to add to the archive. If a folder, everything under the folder will be added to the resulting archive. Default value: $(Build.BinariesDirectory)
I have slightly modified your pipeline.
