Troubleshoot Custom Databases

You can use return errors resulting from your custom database connection for troubleshooting purposes. We will also cover some basic troubleshooting steps for your scripts.

Types of errors

There are three different errors you can return from a database connection:

Error Login Script Description
new WrongUsernameOrPasswordError(<email or user_id>, <message>) Login Occurs when the user's credentials are invalid
new ValidationError(<user_exists>, <message>) Create Occurs when a user already exists in your database
callback(<null>,<false>) Change Password Occurs when the user's password was not updated
callback(<null>) Get User Occurs when the user is not found
new Error(<message>) All Login Scripts Occurs when something went wrong while trying to reach the database

Return errors

To return an error, call the callback function while passing error as the first parameter:

callback(error);

Example:

callback(new ValidationError('email-too-long', 'Email is too long.'));

Returning errors when using Lock

If you use Lock, you can customize the error messages that will be displayed by adding them to the dictionary.

Troubleshooting Errors

Test the script using the TRY button.

If you do not get the expected result or you receive an error, install the Real-time Webtask Logs extension and use console.log() statements in your script and try the connection again. The output of console.log() will print to the Real-time Webtask Logs window.
