Form block does not send emails from widgets

Hello! There was a problem with submitting a form created through a block and displayed through a widget in the footer.

When submitting the form, it always gives an error, I attach a screenshot of the error

We only managed to fix it by adding the block ID to the _kb_form_post_id field via js

jQuery( document ).ready( function( $ ) {
     let blockID = $('.site-footer-middle-section-4 .footer-widget-area-inner section.widget_block').prop('id');
     $( '.footer-form input[name="_kb_form_post_id"]' ).val( blockID );
} );
