Webforms + ajax + recaptcha v3 fallback to alternative challenge

Created on 27 June 2025, about 1 month ago

Problem/Motivation

Hello,

I was not able to use recaptchav3 on webforms with ajax.
There are some issues created for captcha/recaptcha, but none of these solutions/patches worked for me.

I also tried this approach, but it did not fix the issue https://www.drupal.org/project/recaptcha_v3/issues/3356718#comment-15051925 🐛 reCAPTCHA v3 not working in form with ajax elements Closed: works as designed

Steps to reproduce

Download and install webform, captcha and recaptcha v3 module.
Setup recaptcha v3 and create a new action. Set the threshold to ensure captcha v3 will be triggered.
Create a simple webform, using ajax and place the captcha on the 2nd step. Setup for captcha v3 (or import the attached file)
Test the webform, and see that captcha v3 was replaced by the fallback challenge instead of showing the captcha v3 flag.

Please also check the attached files, there is a screencast → describing the bug.

In 🐛 reCAPTCHA v3 not working in form with ajax elements Closed: works as designed , a maintainer said the bug is in the reCAPTCHA module. How did you determine this is a Webform bug?

Hello,

That is a good point.

Yes, they say this is a recaptcha issue, but there is no other way to reproduce this particular error without using webforms.
And also, there is no reported issue on the recaptcha module.

Recaptcha module also do not allow native ajax requests between the forms, and webforms do.

If by anyhow, someone could reproduce this behavior by not using webforms, please let me know, so I can address this to them.
