Hi,
Thanks for the details. I could not trigger the error, as some scripts on the home page are not initialized due to an error on the console: https://i.imgur.com/rhwQRYV.png
It is caused by a 3rd party script, because it is defered, but the inline sript afterwards tries to get a variable from the defered script, which does not exist yet. Try turning off the script defer option in WP rocket, it may resolve this issue, as well as others, and hopefully the one with the search script too.
