Overview

Custom database scripts in Auth0 allow customized authentication and authorization logic. However, debugging these scripts can be challenging. This article explores effective debugging techniques using the Real-Time Webtask Logs extension and console.log statements.

Applies To

  • Custom database scripts
  • Troubleshooting / Debugging

Cause

Custom database scripts may fail due to various reasons:

  • Syntax errors;
  • Incorrect logic;
  • External service dependencies.

Solution

  1. Enable Real-time Webtask Logs Extension:
  2. Install the Real-Time Webtask Logs extension from the Auth0 Marketplace.
  3. Configure it to monitor the custom database scripts.
  4. This extension provides real-time logs, making it easier to track script execution.
  5. Add console.log Statements:
  6. Within the custom database scripts (e.g., login, registration), strategically place console.log statements.
  7. Use them to output relevant information (e.g., variables, conditions).
  8. Check the extension’s logs for these messages during script execution.
  9. Common Debugging Scenarios:
  • Syntax Errors: Review the code for typos, missing semicolons, or incorrect function calls.
  • Data Flow: Log input parameters, intermediate variables, and output results.
  • Conditional Logic: Verify if conditions are met as expected.
  • External Calls: Debug interactions with external services (e.g., API calls).
  1. Iterate and Test:
  2. Make small changes to the script.
  3. Test thoroughly after each modification.
  4. Use the extension logs to identify issues.

NOTE: Effective debugging improves script reliability and enhances the application’s security.
