Target experiences not rendering to page

[traviss1234]

My team has a recurring issue where Target experiences intermittently fail to load in an Angular SPA.

For demo purposes, I have an experiment that is set to be delivered to All Visitors, and 100% of users will get the Challenger. The only modification is a line of custom code to log some text to the console. It is a Page Load modification (not view-based).

When I use the Target-provided QA URL to test the experience, everything works great. However, when we activate the test, it doesn't appear in the delivery request response. (Although we do see a different view-based experiment in the prefetch section of the response.)

The Target lifecycle seems to be broken. Monitoring the lifecycle events, we see:

- at-library-loaded

- at-request-start

- artifactDownloadSucceeded

- at-request-succeeded

- at-content-rendering-start

...but we never see:

- at-content-rendering-succeeded

Has anyone run into this?

Hi @traviss1234 ,

This is quite common issue, particularly with Single-Page Application (SPA) implementations.

The core of the problem is typically related to Adobe Target's lifecycle handling and the interaction with Angular routing or asynchronous rendering of content.

Usually happen due to:

• Angular SPA content loading asynchronously and causing Target to lose context.

• Target modifications are unable to detect the completion of DOM changes.

• Target timing out because it can't confirm modifications rendered successfully.

• Lifecycle events not firing correctly due to Angular’s component lifecycle conflicting with Target’s expectations.

If lifecycle is a frequent issue in your Angular SPA, always explicitly trigger the lifecycle success event after custom code execution:

Example Custom Modification code:

(function(){
// Your custom code here
console.log('Challenger experience loaded successfully');

// Explicitly inform Target lifecycle completed
document.dispatchEvent(new CustomEvent("at-content-rendering-succeeded"));
})();

Recommendations:

• Explicitly dispatch lifecycle events in your custom JS
• Verify Adobe Launch SPA Extension Config (Angular)
• Validate Audience & Activity Priority conflicts
• Transition from Page-load to View-based modification
• Clear cookies/cache to validate consistently

The root cause of your issue is Adobe Target’s inability to confirm that modifications have successfully rendered due to Angular's asynchronous content handling. Explicitly dispatching the at-content-rendering-succeeded event within your custom code is the most immediate, reliable fix.

Ensure the Adobe Launch Target extension is correctly configured for Angular SPA integrations and consider explicitly managing Target’s view lifecycle events moving forward.

Thanks.
