Just moving this into a separate issue for clarity, from here: https://github.com/wp-media/wp-rocket/issues/1561#issuecomment-491105459
This error occurs when Disable Emojis is active:
Commenting out this line resolves it :

HS tags: disable emojis

Another ticket with the issue:
https://secure.helpscout.net/conversation/845945917/106763?folderId=2135277
I confirm that the issue is present in my testing site.
WordPress version: 5.2
PHP version: 7.3
Caldera Forms version: 1.8.4
WP Rocket version: 3.3.3
Before WP Rocket 3.3.3 version, forms failed to submit if 'Disable WordPress embeds' was enable. To submit the form, I had to disable this option. The 'Disable Emoji' option was active.
Now, after the update. I had to swap the options. Un-tick 'Disable Emoji' and tick 'Disable WordPress embeds'.
Please check the following error in browser console:

This issue only triggers for me if both Disable WordPress embeds and Disable emoji options are checked. If I uncheck Disable WordPress embeds but leave Disable emoji checked, the issue is not present. If I uncheck Disable Emojis but leave Disable WordPress embeds checked, the issue is not present.
WordPress 5.2
PHP 7.3.2
Caldera Forms 1.8.4
WP Rocket 3.3.3
