Usually, Adding the <noscript>
block on your page would take care of this... I had gone around this myself on my website
Referring to Google's site (which i visited today after your question, we see the description:
Given these considerations, this Lighthouse audit performs a simple
check to ensure that your page isn't blank when JavaScript is
disabled. How strictly your app adheres to progressive enhancement is
a topic of debate, but there's widespread agreement that all pages
should display at least some information when JavaScript is disabled,
even if the content is just an alert to the user that JavaScript is
required to use the page.
For pages that absolutely must rely on JavaScript, one approach is to
use a element to alert the user that JavaScript is required
for the page. This is better than a blank page, because the blank page
leaves users uncertain about whether there's a problem with the page,
their browsers, or their computers.
I suspect that when you disable javascript via chrome, you might end up with just the text "Please enable javascript"; Try also placing
- an image, a backup navigation (which runs in case of no JS only)
- a backup footer (which runs in case of no JS only)
