Functions are not visible on the Azure Functions and neither function files are visible on wwwroot folder.

Question

Hi ,

Functions are not visible on the Azure Functions and neither function files are visible on wwwroot folder. I've deployed my functions by using VS code. I am not seeing any error on the VS Code side and also not seeing anything on log stream.

Please let me know if you need any logs or so.

Its urgently to be resolved.

Thanks,
Sadaf

Hi @Zaheer. Sadaf (Enterprise Services) , Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

Here are a few things you could check to troubleshoot this issue:

1. Verify the Folder Structure: Ensure that the folder structure of your function app follows the language-specific recommendations. Each function should typically have its own folder with a function.json file.
2. Deployment Method: If you deployed using Visual Studio Code, confirm that you're using the latest Azure Function Runtime Core Tools. Older versions may cause issues with deployment.
3. Check for WEBSITE_RUN_FROM_PACKAGE: If the WEBSITE_RUN_FROM_PACKAGE setting is enabled, it means the wwwroot folder is read-only. You would need to perform a full deployment instead of trying to add functions individually.
4. RBAC Permissions: Make sure you have the right RBAC permissions to deploy functions.
5. Storage Account Connectivity: Verify that your function app has good connectivity to the storage account it uses. You can use the Network Troubleshooter from the Diagnose and Solve Problems blade in the Azure portal to check this.
6. Function App Status: Ensure the function app is up and running. If it’s not, you may see messages indicating that the runtime is unreachable.
7. Check Environment Variables: Make sure that any necessary application settings (like connection strings) are present in the Azure portal under the Application Settings for your function app.

If you’ve double-checked everything and still can’t see your functions, it might help to get some additional information. Here are a few follow-up questions you could consider:

• What type of functions are you trying to deploy (HTTP, timer, etc.)?
• Have you confirmed the function app status—does it show any warning or error messages?
• Can you check the logs in the Azure portal? Are there any specific error messages showing there?
• Did you deploy the functions to an existing Function App, or did you create a new one for this deployment?
• Are you using any specific bindings or triggers that might require additional configuration?

If your functions are not visible in Azure Functions and the function files are not present in the wwwroot folder after deployment, there are a few common issues to consider:

1. Deployment Issues: Ensure that your deployment process is correctly configured to deploy the function files to the wwwroot directory. If the deployment package does not include the necessary files, they will not appear.
2. Folder Structure: Verify that your project has the correct folder structure. The wwwroot directory should contain the deployed function files, and the structure must align with Azure Functions requirements.
3. Build Environment: If you are using a build agent, ensure that it is running on an appropriate environment (e.g., Ubuntu) to guarantee that packages are restored correctly during the build step.
4. Log Stream: Since you mentioned not seeing anything in the log stream, double-check that logging is correctly configured in your Azure Function app settings. This can help identify if there are any hidden errors during the deployment or runtime.
5. Function App Configuration: Make sure that the Azure Function app is configured correctly, including the runtime version and any necessary connection strings.

If these steps do not resolve the issue, consider checking the Azure portal for any additional diagnostics or errors that may not be visible in VS Code.
