Debugging NodeJS on Azure: Solving "You do not have permission to view this directory or page"

Deploying a NodeJS application on Azure can be a seamless process, but sometimes you may encounter the error message: "You do not have permission to view this directory or page." This can be both confusing and frustrating. In this guide, we'll explore common causes for this error and provide practical steps to troubleshoot and resolve it.

Common Causes

Improper Directory Structure

One of the most frequent causes of this error is an improper directory structure. Azure expects your NodeJS application to follow certain conventions:

File Permissions

Another potential issue could be file permissions. When files don't have the right permissions set, Azure may not be able to access them, leading to the error message.

Incorrect Environment Settings

Sometimes, environment settings defined in your Azure App Service may not align with what your application requires. Ensure that all environment variables, especially NODE_ENV, are set correctly based on your application needs.

Troubleshooting Steps

Step 1: Verify Directory Structure

Step 4: Review Environment Settings

Go to your Azure App Service and verify environment settings. Specifically, check the Application Settings section to ensure all configurations align with what's expected in your application.

Step 5: Enable Detailed Error Messages

If you still can't resolve the issue, enabling detailed error messages can offer more insight into what's going wrong. You can do this in the Azure Portal under the “App Service Diagnostics”.
