@Shaik Wasim Ahamed ,

Thanks for reaching out.
please let me know more details about your deployment setup, such as:

What type of Azure DevOps pipeline are you using (e.g., YAML, Classic)?

Can you share the relevant section of your pipeline YAML for the build and deployment steps?

Is your function app located at the root of your source repository, or is it in a subfolder?

Hope this helps you get to the bottom of the issue!

Hi Gaurav.

Sorry i missed your communication thread.
Inside WrapperFunction folder we have init.py__ d function.json.
In the root folder we have requirements.txt, host.json and all other .py files

When i try to zip the whole root folder, I am getting error.

In the pipeline , i dont see any errors at all

Hi @Shaik Wasim Ahamed ,

Thank you for your detailed follow-up. Your situation is a common one, successful Azure DevOps Pipeline deployments but not visible Azure Functions on the portal, usually due to folder structure or zip deployment issues.

Let me summarize the root cause and provide a complete and actionable solution:

Root Cause:

When deploying via ZIP (especially in DevOps pipelines), the root of the zip file must contain the individual function folders (each with __init__.py, function.json), as well as shared files like host.json, requirements.txt.

Your current Structure is causing Issue:

/root-folder │ host.json │ requirements.txt │ main.py │ some_script.py │ └── WrapperFunction/ │ __init__.py │ function.json

When you zip /root-folder, it becomes like this:

root-folder.zip/ root-folder/ WrapperFunction/ host.json ...

This structure is invalid for Azure Function runtime.

This causes the Azure Function runtime not to find any function folders, so no functions appear in the portal, even though deployment appears successful.

Solution: Change folder structure

Restructure your repo or deployment artifact so that the function folder (like WrapperFunction) and host.json, requirements.txt are at the same level in the root of the ZIP.

Correct layout should be like this:

function-app-code/ │ host.json │ requirements.txt │ └── WrapperFunction/ │ __init__.py │ function.json

Steps to implement:

Use correct ZIP command (skip parent folder):

If you're zipping the folder in DevOps or locally, avoid including the parent directory.

cd function-app-code zip -r ../functionapp.zip .

This puts host.json, requirements.txt, and function folders at the root of the ZIP.

Azure DevOps Pipeline Deployment Task

Make sure you're using AzureFunctionApp@1 with correct parameters:

- task: AzureFunctionApp@1 inputs: azureSubscription: '<UrServiceConn>' appType: 'FuncAppLinux' appName: '<UrAppNme>' package: '$(Build.ArtifactStagingDirectory)/functionapp.zip'

After deploying:

Go to Azure Portal > your Function App > Functions tab.

You should now see your function(s) listed.

Hope it helps!

If you have any other questions or still running into more issues, let me know in the "comments" and I would be happy to help you.

Hi @Shaik Wasim Ahamed ,

Thanks for confirming.

Yes, absolutely we shall connect. In the meantime, please follow the steps I've shared, and kindly let me know if you're encountering any issues so we can continue working on the case.

Since your folder structure is already correct.

Then the most likely reason your functions are not showing is:

You’re zipping the whole function-app-code folder, instead of its contents.

That would result in a ZIP like:

functionapp.zip └── function-app-code/ ├── host.json ├── requirements.txt └── WrapperFunction/

It causes the Azure Function runtime to not detect any functions, because it doesn’t expect the extra function-app-code/ folder inside the ZIP.

What You Should Do Instead, CD into the folder

cd function-app-code

Zip only the contents (not the folder itself):

zip -r ../functionapp.zip .

It will create a zip file where the root contains

functionapp.zip ├── host.json ├── requirements.txt └── WrapperFunction/ ├── __init__.py └── function.json

This is the exact layout Azure expects.

After deploying the zip:

Go to Azure Portal > Your Function App > App Service Editor.

Confirm that host.json is directly under /home/site/wwwroot/, not inside /home/site/wwwroot/function-app-code/.

If your Python Azure Functions aren't appearing in the Azure Portal after a successful deployment via Azure DevOps Pipeline, the issue might be with your deployment structure, configuration, or a silent error during deployment. Double-check your package structure, ensure the function folder and host.json are at the root level in the zip file, and verify your deployment configuration to avoid silent errors.

Answer 1

Hi Shaik Wasim Ahamed,

As discussed earlier, you have to host the database in Azure and use ODBC Driver 18 instead of 17 and add the client IP address under firewall rule in SQL Server=>Networking to resolve the issue.

Please try below steps and let me know if you face any issues:

Below are my findings for not able to deploy your function.

ODBC Driver version for SQL Server:

Exception observed:

Result: Failure  
Exception: DBAPIError: (pyodbc.Error) ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 17 for SQL Server' : file not found (0) (SQLDriverConnect)")

You should use ODBC Driver 18 for SQL Server instead of ODBC Driver 17 in SQL_CONNECTION_STRING.

"SQL_CONNECTION_STRING": "mssql+pyodbc://username:password@server/database?driver=ODBC+Driver+18+for+SQL+Server"

Allow Client with IP address ‘[20.XXX.XX.XXX]’ to access the SQL server.

Exception: ProgrammingError: (pyodbc.ProgrammingError) ('42000', "[42000] [Microsoft][ODBC Driver 18 for SQL Server][SQL Server]Cannot open server 'servername' requested by the login. Client with IP address '20.XXX.XX.XXX' is not allowed to access the server. To enable access, use the Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect. (40615) (SQLDriverConnect)")

To know the Client IP address which needs access, go to FunctionApp=>Logs, you can see the ClientIP under Exceptions.

Navigate to your SQL Server=>Networking, Add the client IP address under Firewall rule to allow the access to SQL server.
Add Application setting "AzureWebJobsFeatureFlags": "EnableWorkerIndexing", in the Environment variables of function app and local.settings.json

I have deployed your code to Azure and able to sync the triggers:

8:00:26 PM kpfn2105: Destination directory: /tmp/build/expressbuild 8:00:26 PM kpfn2105: Python Version: /tmp/oryx/platforms/python/3.11.12/bin/python3.11 8:00:26 PM kpfn2105: Creating directory for command manifest file if it does not exist 8:00:26 PM kpfn2105: Removing existing manifest file 8:00:26 PM kpfn2105: Running pip install... 8:00:38 PM kpfn2105: Syncing triggers... 8:00:40 PM kpfn2105: Querying triggers...

8:00:47 PM kpfn2105: HTTP Trigger Urls: http_app_func: https://kpfn2105.azurewebsites.net//%7B*route%7D
