Custom form - Submission fails

I had custom Webforms that weren't working on a site with the Antibot module enabled and protection enabled in the Webforms settings. Once I included {{ element.antibot_no_js }}{{ element.antibot_key }} in the form Twig template, everything worked fine. I only needed to include it once in the template and I did so at the very bottom with some of the other hidden fields like form_token and form_id. This bit of information is no where in the documentation unless I missed it somewhere. Preferably, the module page and the README file. Here is what my block looks like the the bottom of the webform Twig template:

            <div class="row">
                <div class="col-md-2 offset-md-1 offset-lg-2">
                    {{ element.elements.message }}
                    {{ element.elements.url_redirection }}
                    {{ element.form_build_id }}
                    {{ element.form_token }}
                    {{ element.form_id }}
                    {{ element.elements.actions }}
                    # Antibot keys to render.
                    {{ element.antibot_no_js }}
                    {{ element.antibot_key }}
                </div>
            </div>
        </div>
</form>

#18 Worked for my custom forms! Thank you very much jumpsuitgreen! Pretty incredible that this solution was posted at the exact time as I was having the problem.

form_id was returning null or empty when executing form validation logic.
This code _antibot_generate_key($form['#form_id']); in antibot.module

Changed to
_antibot_generate_key($form_state->getValue('form_id'));
Now the form_id is returning the correct value and the form is processed with no antibot related errors.
