rwmb_frontend_validate and empty ID in config

Hi

I have been using front end forms for while without issues since i have used version 4.4.2 (also updated to 4.4.5) for 'front end submission' When i use the 'rwmb_frontend_validate' and check for the config ID it returns empty?

add_filter( 'rwmb_frontend_validate', [ $this, 'productCommentFormValidation' ], 10, 2 );

public function productCommentFormValidation( $validate, $config ) {

	error_log(print_r($config, true));
	
	if ( 'dc-product-comments' !== $config['id'] ) {
		return $validate;
	}	
}

output of php error log (i have only one form in my test environment)
