Splash does not render the full page of a site

[williamlam3611]

Hi, I am trying to crawl this site using splash:
https://www.lithia.com/new-inventory/index.htm

In Splash Web UI, I got this:

The page is not rendered completely, can someone help plz?

My Lua code:

function main(splash)
local url = splash.args.url
assert(splash:go(url))
splash.private_mode_enabled = false
splash.plugins_enabled = true
splash.indexeddb_enabled = true
splash.plugins_enabled = true
splash:set_viewport_full()
time = 10
ok = nil
while (ok == nil) do
ok, reason = splash:wait{time, cancel_on_redirect=true, cancel_on_error=true}
end
return {
html = splash:html(),
png = splash:png(),
har = splash:har(),
}
end

Set a specific viewport value (like: viewport=1920x1080) instead of using full
