I have created a Azure function and I am trying to import another function from different file into function_app.py file. But I see when I tried to deploy on Azure function App, deployment shows success but no function is getting displayed.

I have subscribed to Flex Plan. And my Azure function contain different helper(python) files from where I am trying to import function into function_app.py. I see that when I comment out below line from my code then my function get's deployed on Azure function app and is displayed under overview tab:

from scripts.metadata_file_processing_worker import process_metadata_file, get_file_name_and_extension

But when I uncomment this line then Deployment center shows success but the function is not listed under overview tab. I have attached the directory structure as well. worker_directory

Thank you for using Q&A Platform.

I understand no function is getting displayed, when you tried to deploy on Azure function App while you to import another function from different file into function_app.py file.

When this line is commented out, the function deploys successfully and appears in the Azure Function App Overview tab. But when uncommented, the deployment center shows success, function is not listed under the Overview tab.

Azure Functions may silently fail to load your function if there's an error during import, even if deployment itself succeeds. To avoid this runtime error,

Wrap your import in a try-except block to log any issues. Try this,

from scripts.metadata_file_processing_worker import process_metadata_file, get_file_name_and_extension

except Exception as e:
import logging

This helps finding hidden errors in Azure logs.

Make sure scripts/init.py exists and is not empty. It needs to be there to make scripts a valid Python package. Make sure all dependencies used in metadata_file_processing_worker.py are listed in requirements.txt. Missing packages can cause runtime failures. Open metadata_file_processing_worker.py and confirm thhere are no syntax errors and all imports inside it are valid.

It doesn’t rely on local-only paths that aren’t available in Azure.

Run the function locally using, func start

This will help catch import or runtime errors before deploying.

I hope this helps in resolving the issue, do let me know if you have any further questions on this

@Vaishnavi More please try the below options:

1.
At the top of your function_app.py, add:

import sys
import os
sys.path.append(os.path.join(os.path.dirname(file), 'scripts'))

Then change your import

from metadata_file_processing_worker import process_metadata_file

2.
Move metadata_file_processing_worker.py to the same directory as function_app.py and Update the import:

from metadata_file_processing_worker import process_metadata_file

3.
Include below command in scripts/init.py
from .metadata_file_processing_worker import process_metadata_file

In Addition, Check App Insights Logs, failures often show up in logs even if deployment succeeds. Use func azure functionapp publish with --build-native-deps to ensure dependencies are correctly packaged.Verify requirements.txt includes all dependencies used in scripts/.

I hope this helps in resolving the issue, do let me know if you have any further questions on this
