A Custom Database password change script works when tested directly in the Auth0 dashboard but fails in the live authentication pipeline. This occurs because the Auth0 callback lacks the required success parameter. Resolve this issue by updating the script to return the correct callback parameter to confirm the password change.

The Auth0 test feature often only checks whether the script runs without throwing a fatal error. However, the live authentication pipeline requires the script to return a specific success parameter. The Auth0 callback lacks the required success parameter. Auth0 strictly requires callback(null, true) confirmation of a password change. Returning callback(null) causes Auth0 to treat the action as a failure and abort the flow.

What updates are needed to correct the Custom Database password change script?

Navigate to the Custom Database settings, locate the callback function, and update the script to return a boolean true for the success parameter.

1. Navigate to the Custom Database settings in the Auth0 dashboard and open the Change Password script.
2. Locate the callback function at the end of the successful execution block.
3. Update the callback function to include the success parameter. The callback function takes two parameters: error and success. To indicate a successful password change, the success parameter must be a boolean true. Ensure the script returns callback(null, true) instead of callback(null).
4. Save the changes and test the authentication pipeline to confirm the password change succeeds.

The following example from the Auth0 documentation demonstrates the correct usage of the callback function to return the success parameter.

function changePassword(email, newPassword, callback) {
  // Database logic here
  const success = true;
  
  if (success) {
    // The password change was successful
    return callback(null, true);
  } else {
    // The password change failed
    return callback(new Error("Unable to change password"));
  }
}
