AEM Forms: Adaptive Form submission fails with HTTP 500 due to captcha handler feature toggle

Last update: October 20, 2026

This article explains how to identify and resolve an issue where Adaptive Form submissions in Adobe Experience Manager (AEM) Forms fail with an HTTP 500 error due to a feature toggle enforcing captcha handler resolution.

Description description

Environment

  • Adobe Experience Manager (AEM) Forms
  • Adaptive Forms

Issue/Symptoms

  • Adaptive Form submissions fail with an HTTP 500 error.
  • The error occurs even if the form does not include a captcha field.
  • All forms in the affected environment are impacted.

Cause

A Forms feature toggle forces a captcha handler-resolution step on every form submission. If the handler cannot resolve a captcha validator, the submission fails before reaching any reCAPTCHA configuration.

Resolution resolution

Follow these steps to resolve the issue:

  1. Confirm that Adaptive Form submissions fail with an HTTP 500 error, regardless of whether the forms contain captcha fields.
  2. Review the server logs for errors related to captcha handler resolution or validator extraction.
  3. Contact Adobe Customer Support and provide details about the environment and the observed error.
  4. Ask Adobe Support to review the feature toggle that enforces captcha handler resolution and disable it if necessary.
  5. After Adobe Support confirms that the toggle is updated, perform a hard refresh and retest the Adaptive Form submissions.
  6. Verify that the forms submit successfully without returning HTTP 500 errors.
