A technical reference for the error codes and response codes returned by the Personalization Library, formerly known as Online Engine (OLE), of Acoustic Personalization in the browser console for your channel.

Note: This topic is relevant for the channel developers (for example, website developers) that are using Acoustic Personalization. These error codes are only shown on a console window and are not displayed on the Acoustic Personalization user interface.

Overview

The Personalization Library, formerly known as Online Engine (OLE), of Acoustic Personalization returns an error code or a response code depending on the scenario.

DCIDNF404: Personalized content not available.
Personalization Library returns this response code in any of the following scenarios:
  • No rule matches any of the visitor behavior on the channel, or
  • There is no published rule available for evaluation.
Resolution:
  • To avoid this situation, ensure to create and publish personalization rules that will match the visitor behavior on the channel.
  • To handle this response code, you must specify the default content to be shown to the visitor in the case no rules are available or no rules match the visitor behavior.
DOM100: <ContainerID> is not a valid HTML element.
This error code indicates that the specified element is not a valid DOM object.

Error resolution: Verify the HTML elements and JavaScript code in the specified container of the channel, and make necessary changes so as to make the container a valid DOM object.

CAR204: Visitor activity data not available.
This information message is displayed if the caricature data is not available for the specified zone ID. This may happen in the following scenarios:
  • The visitor is visiting the channel for the very first time, and hence caricature data is not available.
  • There are no matching rules for the visitor behavior on the channel, and hence caricatures are not generated.
  • No events are generated on the channel page to create the caricatures.
Resolution: If the caricature data is not available for a repeat visitor (that is, a visitor who has visited the channel before), verify the following aspects:
  • Check if the channel tenant ID is correctly set.
  • Confirm whether the caricature API URL is proper and is returning a valid response.
  • In the Acoustic Exchange test drive, verify that the required events are delivered to the test drive.
If the issue persists after these actions, contact the Acoustic Personalization Support team.
