Console error related to Guide Bridge after AEM LTS upgrade

[shreyashruti]

Hi,

I am facing an issue where I am seeing console error for all the modal classic adaptive forms after AEM LTS upgrade. As a result of which, when I load the forms which are in modal it's not populating with proper values.

The forms version that we have installed as a part of LTS upgrade is 6.1.152. I am struggling to identify the root cause.

Kindly suggest/advice. Thank you in advance.

Regards,
Shreya

Hi @shreyashruti ,

Based on your description, this appears to be a Guide Bridge initialization issue after the AEM Forms LTS upgrade. Here's what's likely happening and how to address it:

The Guide Bridge library (which handles adaptive form rendering and data binding) may not be loading correctly or has compatibility issues with version 6.1.152.

Check the console error details - Look for specific error messages mentioning guideBridge or GuideBridge is not defined
Verify clientlib dependencies - Ensure the Guide Bridge client libraries are properly included and loading in the correct order in your modal implementation
Check for JavaScript conflicts - The upgrade may have introduced script loading order issues or conflicts with custom code
Review the modal initialization timing - Forms in modals often fail when Guide Bridge isn't fully initialized before the form renders. Add a check to ensure guideBridge is ready before populating values
Apply latest patches - Check if Adobe has released any hotfixes for version 6.1.152 that address Guide Bridge issues

Add a delay or use the guideBridge.connect() callback to ensure the bridge is ready before attempting to set values in your modal forms.
I'd recommend checking Adobe's release notes for 6.1.152 and opening a support ticket if this is a known regression issue.Claude is AI and can make mistakes. Please double-check responses.

Hi @shreyashruti — are there any bundles in an Installed state, specifically those related to Adaptive Forms?

Also, could you check the Network tab to see if the data is coming back? That should help narrow down whether this is a JS issue or a Java-side error.

Hi @Lokesh_Vajrala ,

All the bundles are in the active stage, and the data is being retrieved correctly. The issue occurs specifically when we try to populate the data. The snippet below is the part that’s causing the error due to guideBridge. I’m attaching the code for reference.
