Modular form error validation

Support Forms & Blueprints
1

I am struggling to customize the contact form with the Skeleton Agency theme to work. The contact form works out-of-the-box. I am getting tons of spams emails, so I have added the honeypot, but that isn’t working too well. Someone on here suggest blocking links in the textarea box.

I have added the validation pattern for not allowing links in the textarea. This works; however, the form does not give an error message. The user maybe confused thinking the form was send successfully which it did not.
