Azure Function App - Deployment successful but code is not updated

Nikhil 41

I developed a function few days ago, deployed it and it was working fine. Later I made few more changes to the code and deployed few times. It was working fine.

Since yesterday, when I try to deploy a new change. Deployment says it is successful but the code is not getting updated in the function app and I'm getting the alert function is unreachable.

Pricing plan : B1

AzureWebJobsStorage: It is pointing to the correct storage account and folder exists.

WEBSITE_RUN_FROM_PACKAGE is set to 1.

Run time : Python

@Nikhil Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I understand that you are unable to update your Azure Function App's code despite successful deployment. You are using a B1 pricing plan, have confirmed that AzureWebJobsStorage is pointing to the correct storage account, and WEBSITE_RUN_FROM_PACKAGE is set to 1. The runtime is Python.

Could you please let me know if you are seeing the error function is unreachable on the function app portal ?

Could you provide me the complete error message with relevant screenshot ?

Did you try restarting the function app and check if that makes a difference ?

Could you please make sure that the d:\home\data\SitePackages (Windows) or /home/data/SitePackages (Linux) folder has a file named packagename.txt ?This file contains only the name, without any whitespace, of the package file in this folder that's currently running. Then also open the d:\home\site\wwwroot (Windows) or /home/site/wwwroot and check if your updated code is present here. This step is to isolate that you deployment is done successfully.

Could you please follow this article and check if you still see the same issue ?

Awaiting your reply.

@navba-MSFT , Here are my answers.

Could you please let me know if you are seeing the error function is unreachable on the function app portal ?

Yes, After deploying, all my python files are blank and I see "function is unreachable"

Could you provide me the complete error message with relevant screenshot ?

There is no error message.

Did you try restarting the function app and check if that makes a difference ?\

Same issue after restarting the function app.

Could you please make sure that the d:\home\data\SitePackages (Windows) or /home/data/SitePackages (Linux) folder has a file named packagename.txt ?This file contains only the name, without any whitespace, of the package file in this folder that's currently running. Then also open the d:\home\site\wwwroot (Windows) or /home/site/wwwroot and check if your updated code is present here. This step is to isolate that you deployment is done successfully.

packaganame.txt has the new packagename that I deployed

/home/site/wwwroot has the old python code.

Could you please follow this article and check if you still see the same issue ?

Followed the article.

AzureWebJobsStorage is correct.

Storage account credentials are correct.

Docker logs doesn't have any errors.

@Nikhil Thanks for your reply. I have followed your above steps and tried the same set-up at my end.

I am able to update my code and able to perform the deployment. Also note that my updated content is also visible on the portal (Function App) and it reflected the updated content too.

Could you please perform the deployment as mentioned in this document and check if that helps ? If you have tried it already try publishing with func azure functionapp publish command (see here) and check if that makes a difference.

Alternatively, please try the Zip deployment through CLI and check if that helps to push the new and updated content.

Also check if the same issue happens with a different ( newly created) function app too.

Awaiting your reply.

@navba-MSFT

I tried the methods you suggested and it didn’t work.

I was able to deploy the same code on a new function app without any issues.

@Nikhil Thanks for the update. I am glad that on the new function app it is working fine as expected. If you wish to identify the root cause of the non-working scenario, I would recommend opening a support ticket with Microsoft.

Hello, for a similar issue where deployment is successful to the function app but code is not updated. Delete the app setting - WEBSITE_RUN_FROM_PACKAGE. Try deploying again. This worked for me.
