AEM Forms Core Components – Wizard breaks the authoring UI

[mancillaignAdobe]

Hi everyone,

I’m running into a blocking issue with Adaptive Forms Core Components in AEM as a Cloud Service, specifically when using the Wizard component. I wanted to check if anyone has seen something similar or has a workaround.

Environment

• AEM as a Cloud Service: 2025.11.23385.20251113T172403Z-251100

• AEM Forms: 2025.10.17.02-251100

• Project created using aem-project-archetype 56 with:

  • aemVersion=cloud

  • includeFormsenrollment=y

  • includeFormscommunications=y

  • includeFormsheadless=n

  • includeDispatcherConfig=y

No custom clientlibs, no overrides — completely OOTB.

Issue

When adding a Wizard (Adaptive Forms Core Component) to a form in the editor, the entire authoring UI breaks immediately.
I can’t add more components and the editor becomes unusable.

This is the error shown in the console:

Uncaught TypeError: Class constructors cannot be invoked without 'new'
at new d (contentframe.lc-81f5c390f95e08480e74aac0a31c33c0-lc.min.js:13:87)
at b (contentframe.lc-81f5c390f95e08480e74aac0a31c33c0-lc.min.js:12:113)
at a (contentframe.lc-81f5c390f95e08480e74aac0a31c33c0-lc.min.js:14:243)
at contentframe.lc-81f5c390f95e08480e74aac0a31c33c0-lc.min.js:14:392
at contentframe.lc-81f5c390f95e08480e74aac0a31c33c0-lc.min.js:15:5

The stack trace always points to contentframe.lc-….min.js, which is part of the authoring ContentFrame clientlibs.

What I’ve already checked

• Happens only in the authoring UI (editor).

• Reproducible on clean forms created from OOTB Core Components templates.

• No custom code, no extra clientlibs.

• Using Chrome, also reproduced in Incognito (no extensions).

• Other components work fine — the issue is triggered specifically when dropping the Wizard.

Steps to reproduce

1. Create a new Adaptive Form (Core Components) using an OOTB template.

2. Open it in the editor.

3. Drag & drop a Wizard component.

4. The editor immediately throws the JS error and stops working.

Hi @mancillaignAdobe , I tried replicating the issue you mentioned, but I am able to add different components post adding wizard component in Form, though while rendering I could see renderation issue, but no issue while Authoring.

Previous version does not show the behaviour which I mentioned.
can you share the project you created, let me check it at my end.
