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);

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, 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.
