Troubleshooting Application Errors

Encountering an application error can be frustrating. This section provides guidance on common error types, their causes, and step-by-step solutions to help you resolve them quickly.

Common Application Errors

Error Code: 500 Internal Server Error

This error indicates that something went wrong on the server, but the server could not be more specific about what the exact problem is.

[Error Details: An unexpected condition was encountered.]
Try refreshing the page. If the problem persists, contact support.

Error Code: 404 Not Found

The server cannot find the requested resource. This usually happens if you typed the URL incorrectly or if the page has been moved or deleted.

[Error Details: The resource you requested could not be found on this server.]
Double-check the URL for typos. Navigate back to the homepage and try again.

Error Code: 403 Forbidden

You do not have permission to access the requested resource. This could be due to authentication or authorization issues.

[Error Details: Access to this resource is denied.]
Ensure you are logged in with the correct credentials. Check your user permissions if you are an administrator.

Error Code: Database Connection Error

The application failed to connect to its database. This could be due to network issues, incorrect credentials, or the database server being down.

[Error Details: Unable to establish connection to database server. Reason: Connection refused.]
Verify database server status and network connectivity. Check database credentials in the application configuration.

Error Code: Uncaught TypeError

A JavaScript error occurred, preventing script execution. This is often due to trying to access a property of an undefined variable.

[Error Details: Cannot read properties of undefined (reading 'propertyName')]
Inspect browser developer console for specific line numbers. Review recent code changes for potential null or undefined variable issues.

Troubleshooting Steps

  1. Check Browser Console: Open your browser's developer tools (usually by pressing F12) and navigate to the "Console" tab. Look for any error messages, especially those in red.
  2. Clear Cache and Cookies: Sometimes, corrupted cache data can cause unexpected behavior. Try clearing your browser's cache and cookies.
  3. Try Incognito/Private Mode: This helps determine if the issue is related to browser extensions or cached data.
  4. Restart Application/Server: If you have administrative access, try restarting the application or the server it runs on.
  5. Review Logs: Examine application and server logs for more detailed error information.
  6. Consult Documentation: Refer to specific error code documentation or guides for your application.
  7. Contact Support: If you've exhausted other options, reach out to our support team with detailed information about the error.
