I tried including a file like this:

I use woody snippets for php shortcodes. While it works with divi, it does not with bricks. This is the content of the shortcode:

<?php include ("folder/file.html"); ?>

It works with text only content, and the normal echo: hello world works too. Is there a problem with including a file like this? If I use the php snippet above in the code element I get php warnings.
