Trying to submit form without entering captcha throws error

We have a strange issue. If you try to submit the form (which is using the GF Survey addon), the form will sit and spin with an error in the console. The user will have to refresh the page and start over to get past the issue.

The form will not display the proper errors for required fields not being filled in if you try to submit the form blank.

The site is using Elementor with the Essential Addons Gravity Forms widget submitting the form via AJAX.

This screenshot shows the spinner and lack of errors on the fields.

This screenshot shows the error in the console.

Any help is appreciated!
