Signature field makes form disappear

I’m on WP Engine and setting up a form with a signature field. When I preview the form, everything loads fine. But when I add it to a page and view the front end, the form is gone. If I remove the signature field, the form returns. Here is the error in the console. Any advice would be appreciated. I’ve cleared my cache numerous times, tried multiple browsers, private browsing modes and all.
