Azure functions not showing on portal, even though deployment was successful

Question

Azure functions not showing on portal, even though deployment was successful

Ayleen Durasno 5 Microsoft Employee

Hello. I am using an ADO pipeline to deploy my azure function app to a staging slot. Although the deployment is successful, the functions do not load in the portal overview tab and I hit a 404 error when triggering the endpoint. I tried deploying manually using zip deploy and it worked as expected, am just facing the issue with pipeline deployment

Hi Ayleen Durasno,

Thanks for reaching out to Microsoft Q&A.

Please share below details to investigate the issue further:

Can you share the specific Azure Function Runtime version you’re using?

Have you checked the Application Settings for any missing configurations or incorrect values?

What specific settings are configured in your ADO pipeline for deployment?

Are you using any internal networks or restrictions that could block outbound calls?

Have you reviewed any diagnostic logs if Application Insights is enabled?

@Pravallika KV , Below is the information you requested:

4.1045.100.0

Yes, there aren't any discrepancies

It is deploying a zip folder from the build pipeline to the function app slot. No settings aside from azureSubscription, appType, appName, packahe, deployToSlotOrASE, resourceGroupName, and slotName.

Not that I am aware of. When I deployed using a zip deploy method manually it was able to be invoked normally.

I have, there is no stack to trace, just a 404 error since the function is not found.

I have the same issue.
A week ago, deployment was smooth and once it is written deployment successful, it will be reflected on my Azure Function App. This week once, I tried to deploy with "Deployment successful" message on my local by using "func azure functionapp publish <my_azure_function_name>", but the project files are not updated on Azure Function App. I checked in site/wwwroot of the DebugConsole (Kudu), and nothing is reflected.

It sounds like you might be experiencing a runtime issue rather than a deployment issue since the functions are not showing up in the Azure portal after a successful deployment through the ADO pipeline. Here are a few things to check:

Storage Account Access: Ensure that your function app has access to the required storage account. If the function runtime can't access the storage, it may not start correctly.
Deployment Package: Verify that the deployment package generated by your pipeline is correctly structured and includes all necessary files. The package should be loadable into the /home/site/wwwroot directory.
Configuration Settings: Check your function app configuration settings, such as the runtime or language version and any connection strings for triggers. Incorrect settings can prevent the function host from starting.
Deployment Logs: Review the logs from your ADO pipeline deployment to see if there are any warnings or errors that might indicate what went wrong during the deployment process.
Function Triggers: Ensure that the triggers for your functions are set up correctly and that any external dependencies are accessible and configured properly.

If you've checked these areas and are still encountering issues, you might want to consider running the Azure Function App Diagnostics to help identify any underlying problems.
